1. An airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is approximately normal with = 15.5 and = 3.6.

a)In one week, what is the probability that the airline will lose between 10 and 20 suitcases?

b)In one year, how many weeks would you expect the airline to lose between 10 and 20suitcases?

-can you please breakdown the steps, not just an answer please.

Thank you :)
