Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.6

5.6 per year.

a. Find the probability that, in a year, there will be 3

3 hurricanes.

b. In a 45-year period, how many years are expected to have
3 hurricanes?

c. How does the result from part (b) compare to a recent period of 45 years in which 4 years had 3 hurricanes? Does the Poisson distribution work well here?

answer: 59

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
