Question

Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial.

n equals 20​, x equals 16​, p equals 0.75

​P(16​)equals nothing ​(Round to three decimal places as​ needed.)

Answer 1

Solution

Given that ,

p = 0.75

1 - p = 0.25

n = 20

x = 16

Using binomial probability formula ,

p(16) = 0.190
