with p=.02 and r = 3
(1) How many times would you expect to toss a balanced coin in order to obtain the first head?
Geometric p=.5
OR
Negative binomial with r = 1 and p=.5
(2) A new surgical procedure is successful with a probability of .8. Assume the operation is
performed 5 times and the results are independent of one another. What is the probability
that all five operations are successful?
Binomial n = 5 p=.8
(3) A jury of six persons was selected from a group of twenty potential jurors, of whom eight
