Question

Forty percent of all high school graduate work during the summer to earn money for college tuition for the upcoming fall term. Assuming a binomial distribution, if 6 graduates are selected at random, what is the probability that none of the graduates have a summer job

Answer 1

`0.0467` is the probability that none of the graduates have a summer job

Explanation:

Here

P
`= 0.40` and n
`= 6`

Probability that none of the graduate gets job

this means that x = 0

P (x = 0)
`= ^6C_0 * (0.40)^0 * (0.60)^6`

P (x = 0)
`= 0.0467`
