A Department of Transportation report about air travel found that nationwide, 76% of all flights are on time. Base the following questions on 125 randomly selected flights. You may assume the only outcomes are that a flight is either late or is on time. (For all probabilities round to tenth of a percent ) a) How many flights would you expect to be late

Answer:30 flights are expected to be late.Step-by-step explanation:Consider the provided information.A Department of Transportation report about air travel found that nationwide, 76% of all flights are on time.That means 100-76% = 24% of all flights are not on time.125 randomly selected flights.We need to find flights would you expect to be late.Flight expect to be late E(x) = nqHere n is 125 and the probability of late is 24 or q = 0.24Thus substitute the respective values in the above formula.Flight expect to be late E(x) = 125 × 0.24 = 30Hence, the 30 flights are expected to be late.
