Question

Find the probability of 5 successes in 9 trials of a binomial experiment in which the probability of success in any one trial is 37%.

Answer 1

0.1376

Explanation:

We will use the binomial formula here

Where p = 37% = 37/100 = 0.37

1-p = 1-0.37 = 0.63

So we have

P(x = 5) = 9C5 * 0.37^5 * 0.63^4 = 0.1376
