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= 6, x= 3, p= 1/6

Answer 1

0.054

Explanation:

We have the general binomial probability calculation as;

n C r * p^r * (1-p)^(n-r)

Where 1-p = 1-1/6 = 5/6

So we have ;

6 C 3 * (1/6)^3 * (5/6)^3

= 0.054
