A binomial event has n = 60 trials. The probability of success for each trial is 0.20. Let x be the number of successes of the e
OLga [1]

Answer:

12 and 3.0984

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

\mu_{x} = np

The standard deviation of the binomial distribution is:

\sigma_{x} = \sqrt{np(1-p)}

In this problem, we have that:

n = 60, p = 0.2

So

\mu_{x} = np = 60*0.2 = 12

\sigma_{x} = \sqrt{np(1-p)} = \sqrt{60*0.8*0.2} = 3.0984

So the correct answer is:

12 and 3.0984
