Question
According to New Jersey Transit, the 8:00 a.m. weekday train from Princeton to New York City has a 90% chance of arriving on
time on a randomly selected day. Suppose this claim is true. Choose 6 days at random. Let Y = the number of days on which the
train arrives on time.
What is P(Y = 4)? Interpret this value.
(0.90)4 (0.10)². There is a 0.66% probability that exactly 4 of the 6 trains arrive on time.
(0.90) ¹ (0.10)². There is a 0.66% probability that at least 4 of the 6 trains arrive on time.
This probability cannot be calculated because this is not a binomial setting.
O()(0.90)+ (0.10)². There is a 9.84% probability that at least 4 of the 6 trains arrive on time.
O()(0.90)4 (0.10)². There is a 9.84% probability that exactly 4 of the 6 trains arrive on time.
