An airline knows from experience that the number of suitcases lost each week is normally distributed with a mean of 21.4 and a standard deviation of 4.5. Assuming a Poisson distribution, what are the probabilities that in any given week they will lose:

a) exactly 25 suitcases?

b) at most 25 suitcases?

If this is a normal distribution, what are the probabilities that in any given week they will lose:

c) exactly 25 suitcases?

d) at most 25 suitcases?
