Hurricanes in a particular place arrive with a mean of 2.75 per year. Suppose the number of hurricanes can be modeled by a Poisson distribution with this mean. a) What's the probability of no hurricanes next year? b) What's the probability that during the next two years, there's exactly 1 hurricane?

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

step-by-step explanation:

the true ones are a b and d

true
