If Aaron tunes into his favorite radio station at a randomly selected time, there is a 0.20 probability that a commercial will be playing. b. If Aaron tunes into this station at 5 randomly selected times, will there be exactly one time when a commercial is playing?

Yes, there will be with a probability of 0.4096

Step-by-step explanation:

Given,

p = 0.2

1 - p = 0.8

Number of trials, n = 5

P(x = 1)

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 1) = 5C1 * 0.2^1 * 0.8^4

P(x = 1) = 5 * 0.2^1 * 0.8^4

P(x = 1) = 0.4096

Yes, there will be with a probability of 0.4096
