a. In a battleground state, 36% of all voters are Republicans. Assuming that there are only two parties - Democrat and Republican, if two voters are randomly selected for a telephone survey, what is the **probability** that they one is a Democrat followed by a Republican? Round your answer to 4 decimal places.
The **probability** that the first person chosen is a democrat = 64%
Now, the...

The Use of **Probability** in Inferential Statistics
Statistics use assumption on population distribution to estimate population values based on sample values (Kemp & Kemp 257-66). **Probability** distributions functions or simply distribution functions are used (Soong 39-41). The distribution function associates a variable value with a **probability** (Soong 39). This can take the form Fx(x) =P(Xx) where the lowercase x refers to a specific value of a variable. **Probability** distribution functions have shapes represented by the mathematical equations. The areas under the curves or distribution functions are associated with **probabilities**.
In business statistics, some of the distribution functions that are often used are the Z-statistics, t-statistics...

.... It means that is there is nothing certain and exact associated with an event, and that happenings are uncertain and there are **probabilities** that are associated with them. **Probability** can be defined as the study that is concerned with locating certainty in uncertain events. **Probability** is known as the method of weighing evidence and opinion about uncertain and complex environment. Christiaan Huygens is supposed to be the first person to treat **probability** with scientific principles to provide a more refined form of the term in the year of 1657. There are several functions of **probabilities**. Distributions are considered one of them. These functions are used to assign the possible and **probable** events to the entire series of the events...

... to incorporate a duplicate set of components, than a task will fail if both of the same task simultaneously breaks down (Both B1 and B2 fails or Both C1 and C2 fails, or Both D1 and D2 fails). Let the **probability** of at least one component of B, C and D is working is given by P(BW), P(CW) and P(DW), respectively. Therefore,
All tasks (A1, BW, CW, and DW) are independent tasks. Therefore, the **probability** that the machine completes its process from start to finish after incorporating duplicate set of components for tasks B, C and D is
The duplicate set of components amendments will improve the performance of the machine to about 82.84% that is now the machine efficiency is about 82.84%.
iii. The machine efficiency heavily depends on the first...

...= the possibility 6/48, 7/48
After showing of the cards, the following are the **probability**= 6 diamonds occurring= 6/48
= 3 diamonds occurring= 3/48
7 diamonds occurring= 7/48
From this calculation, there is little possibility, (3 of 52,) of three coming up again. **Probability** also do not repeat itself and therefore the **probability** of three coming up again is still little if reasoning from the same line of thought. This therefore supported my need to continue playing because I knew my down cards could come up instead of the three of diamonds.
The possibility of 4 flower coming up again is nil, because the 4 only occurs once.
The possibility of the 9 coming up again is also...

... A 7-card hand is chosen from a standard 52-card deck. a. How many of these will have four spades and three hearts?
Number of ways to pick four spades = 13 C 4 = 715
Number of ways to pick three hearts = 13 C 3 = 286
Therefore, there would be [13 C 4 * 13 C 3] = 204,490
b. What is the **probability** that we draw a hand composed of precisely four spades and three
hearts?
Number of ways to pick 7 cards randomly: 52 C 7 = 133,784,560
Therefore, **probability** = [13 C 4 * 13 C 3] / (52 C 7) = 0.001528

.... An offspring therefore, independently, and randomly, derives one of each pair of chromosomes from each of the parents. **Probability** therefore helps to understand chances and possibilities of genetic compositions of offspring based on their parents’ genetic compositions (Olofsson, p. 56).
This paper seeks to investigate **probabilities** of outcomes of events in tossing two sided coins. The paper will explore and compare the experimental and theoretical **probabilities** from tossing the coins for conclusions over inheritance of genes.
Methods
The experiment was conducted by repeatedly flipping a coin. With twenty events, observations were made for head, tail, and frequencies recorded. The experiment was repeated with two simultaneous tosses...

...of eleven heads and nine tails. Although flipping a coin is said to have an equal chance of coming up on either side, one’s experience did not have such a result. This may be due to the fact that the experiment was only made twenty times. According to frequentists, “the **probability** of getting a heads is 1/2, not because there are two equally likely outcomes but because repeated series of large numbers of trials demonstrate that the empirical frequency converges to the limit 1/2 as the number of trials goes to infinity” (Edurite.com, n.d.).
` When one played the dice roll, one realized that the outcomes are much more than the coin flip because each die has six sides. The other die has also six sides; thus, rolling the...

... of strategies employed by organizations. Moreover, the statistical findings influence the planning and allocation of resources within organizing. For criminal justice agencies, the crime reports provide critical information used for evaluating crime levels. The public use the statistics to hold the individual and agencies in the criminal justice system accountable for the state of security in the country.
Question 2.B.
Critical decisions within organizations concern the future. However, the unpredictability of the future makes it had to make good decisions. Consequently, mangers of these organizations must make apt prediction about the future based on some assumptions. This requires knowledge of uncertainty, which is the **probability**...
