Relationship between Exponential and Poisson Distributions?
Poisson distribution shows the probability of a given number of events occurring in a fixed interval of time. Example; if average of 5 cars are passing through in 1 minute. probability of 4 cars passing can be calculated by using Poisson distribution. Exponential distribution shows the probability of waiting times between occurrences of events. If we use the same example; probability of a car coming in next 40 seconds can be calculated by using exponential distribution. -Poisson : probability of x times occurrence -Exponential : probability of waiting times between events.
You think you have a 95 percent chance of passing your next business statistics exam This is an example of which approach to probability?
an optimistic one
What is the probability that 8 of the next 10 who take the exam will pass given a success chance of 97 percent?
To work this out, you first need to calculate the probability of the first 8 passing, and the final 2 failing. That is 97%8x3%2 which equals 0.070536902349392649% The next step is to find out how many different ways the people can be ordered. We have 10 in total and want to order 8, so the number is 10C8, which is 45. Multiply this by the above probability and you get 3.174160605722669205% Thus the probability that 8 of the next 10 will pass is 3.17%

Where does the electricity go after passing any appliance?
It 'travels', via the transmission and distribution systems, to the load (i.e. factories, residences, etc.).
You were involved in an accident where a car was stopped to turn right the second car was passing on the shoulder and you hit this car who is to blame?
Assuming you are in the car that stopped at the light and you hit the car that was passing, It is obvious the car passing illegally on the right gets the ticket and the blame and had better have insurance.
How do you solve this problem there are 3 sets of examination in a vocational TESDA course the probability that an examinee will pass in each subject is 80 what is the probability that an examinee pas?
The problem as I understand it is the examinee must pass test 1 and test 2 and test 3. Therefore, the probability of passing all 3 exams is .8*.8*.8 = 0.512.
I need to meet with twelve people. I only have eight appointments. What is the probability of seeing them all that day?
The answer depends on whether you seeing them - in passing - is enough to qualify as seeing them or whether you actually need to meet with them. If you do need to meet with all twelve and are meeting them only one at a time, then the probability is 0. If you can call group meetings, the probability can be raised to 1.
