According to an airline, a particular flight is on time 88% of the time. Suppose 42 flights are randomly selected and the number of on time flights is recorded. Find the probabilities of the following events occurring. a. All 42 flights are on time b. Between 34 and 36 flights (inclusive) are on time

Step 1
All 42 flights are on time This is a binomial distribution problem where we have n=42 trials (flights), each with a probability of success (being on time) of p=0.88. We want to find the probability that all 42 flights are on time, which is k=42 successes. The Show more…

According to an airline, a particular flight is on time 92% of the time. Suppose 31 flights are randomly selected and the number of on time flights is recorded. Find the probabilities of the following events occurring. a. All 31 flights are on time b. Between 25 and 27 flights (inclusive) are on time

At Denver International Airport, 86% of recent flights have arrived on time. A sample of 14 flights is studied. Round the probabilities to four decimal places. (a) Find the probability that exactly 12 flights were on time. (b) Find the probability that 12 or more flights were on time. (c) Would it be unusual for 13 or more flights to be on time? It would not be unusual for 13 or more flights to be on time since the probability is ___.
