Once the elevator reaches the ground floor, it will have a 100% **probability** of going up, and when it reaches the 10th floor, it will have a 100% **probability** of going down. The elevator goes up and down at discrete intervals. Reflection at the barriers is represents the points when the elevator is at the ground and the 10th floors.

...Be sure to show your work so that partial credit may be awarded. To receive full credit, work must be shown if applicable. Section 3 Basic Concepts of **Probability** and Counting
1. Lock combinations are made by using 4 digits. How many different lock combinations can be made if repetition of digits is allowed?
Each place in the 4 digit number can be occupied by any of the 10 digits. Hence by the multiplication theorem of **probability**, we get
No of different combinations = 10 × 10 × 10 × 10 = 10000 combinations
2. In 2001 the stock market took some big swings up and down. One thousand investors were asked how often they tracked their investments. The table below shows their responses. What is the...

...The Use of **Probability** in Inferential **Statistics** There are many distribution models used in inferential **statistics**. The distribution modelsreflect a statistician’s assumption on how variable values are possibly distributed in a population. Based on sample data and assumptions on the population distribution, **inferences** are made on how the variable values may be actually distributed in a population. The most conventional or usual assumptions on population distribution are the standard normal, t-distribution, and the chi-square distribution.
Using assumptions on how variable values are distributed in a population makes it possible for man to anticipate the characteristics...

...What are the Historical facts Behind the Development of **Probability** and Distribution? Introduction **Statistics** is the field that is concerned with investigation, summarizing and **inferring** from facts relating to complex systems. History shows that various **statistical** tools such as **probability** and distribution methods were developed around the sixteenth century. The time period when these marvelous mechanisms were established was the scientific revolution. Some efforts regarding **probability** were also made in the 15th century in the context of dice throwing but the finished and established version came to light only in the sixteenth...

...Your full ID: Assignment 02-**Probability** Module + Hand Out “**PROBABILITY**” i. Given: P(A) = 6/7, P(B) = 7/8, P(D) = 9/10, and Machine efficiency = 27/44
P(C) = unknown
All four components need to be in working order for the machine to complete the process successfully. The machine will fail to complete the process from start to finish if at least one of the tasks fails. The efficiency of the machine is the **probability** that the machine completes the process from start to finish. Further, all tasks (from A to D) are independent tasks Therefore,
Therefore, the **probability** that component C is in working condition is
The **probability** that component C is in...

...**PROBABILITY** Explain your strategy for solving the problem I will not call my opponents bet by tossing the rest of my money because in playing cards winning lies on **probability**. I would continue with my two down cards 6 of (diamonds) & 7 of (diamonds) bearing in mind that they will come up.
Explain why your strategy will work.
**Probability** does not always occur twice, so there is no need for quitting. My strategy therefore largely lies on **probability**. **Probability** is always related to gambling because if at all one of the down cards does not show up there is a high possibility that they will come up in the next play (Bassarear 2011).
Execute your strategy showing your mathematical work.
So am having the values diamonds=6, 7... = the...

...Task A A is looking for the best option in purchasing school supplies. Company A is offering a discount of 10% for every dollar amount spent;Company B is offering a higher
discount of 20%, but the discount is only applicable after a $20minimum is spent on supplies.
The student is looking for the company that will save her the most amount of money overall. Given that she is on a fixed income it will be important for her to receive the highest amount of savings when she purchases school supplies. It needs to be determined which company would save the student the most amount of money.
There are two options for the student to consider:
Firstoption is to purchase from company A, assuming it offers a discount of 10% on each dollar... A A is...

...of significance and conclude that there is no correlation between the scores of the countries when playing home and away. Although there is supposed to be a correlation between home and away scores, it must be realized that home advantage every team every differently.
A third test on the correlation between the interaction of the sum of score of different countries yields similar results. From this test, a p-value of 0.623 and F-tabulated value 0.757 are obtained. Based on these values, there is enough evidence to reject H0 at 95% level of significance and conclude that there is no correlation between the interaction of the sum of score of different countries yields similar results. There could have been some interaction as each country...

...Ranking of Jackson County judges Ranking of Jackson County judges Every year a number of cases are handled by judges in Jackson County. Some of these cases are appealed. However some of them are upheld. In connection to this the main aim of these study was to investigate how the judges perform based on the number of cases appealed and the number of cases reversed. This ranking was necessary to find out whether the judges are doing a great or not. Three courts were investigated: Municipal Court, Domestic Relations, and Common Pleas Courts.
To get the **probability** of appeal: P (Appeal), the following formula was used;
P (Appeal) =
To obtain P (reversed), the following formula was used.
P (Reversed) =
On the other hand P...
