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

Answer:

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

Step-by-step 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) $= 0.0467$
