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 theprobability of success on a single trialn=6x=2, p=0.25P(2)=(Round to three decimal places as needed.)

Answer 1

n = 6

x = 2

p = 0.25

Binomial distribution gives the probability of x successes among n trials as:

Where q = 1 - p = 0.75

Then:
