The probability that a train leaves on time is 0.9. if esme takes the train 10 times, how many times can she expect to be on time?

Step-by-step explanation:

The probability that she leaves on time is .9

To find out how many times she will leave on time, take the probability times the number of events

on time departures = P(on time) * departures

                                   = .9 * 10

                                    =9

She should leave on time 9 times
