Question

During a single day at radio station WMZH, the probability that a particular song is played is 1/5. What is the probability that this song will be played on exactly 3 days out of 5 days? Round your answer to the nearest thousandth.

Answer 1

the probability that the song should be played on accurately 3 days out of 5 days is 0.051

Explanation:

Given that

The probability that a particular song is played is 1 by 5

We need to find out the probability that the song should be played on accurately 3 days out of 5 days

So,

`P(x = 3) = (5!)/(3! (5 - 3)!) ((1)/(5))^3(1 - (1)/(5))^(5-3)`

= 0.051

Hence, the probability that the song should be played on accurately 3 days out of 5 days is 0.051
