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?

9

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

n

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
