Question 931606: POISSON PROBABILITY DISTRIBUTION
Question.
According to the mortage bankers association of america, the foreclosure rate on mortages in 2001 was 1%, assuming that this rate is applicable to a community where 1000 homes have mortages, use the poisson approximation to the binomial distribution to determine the following for X= the number of foreclosures in this community during the coming year.
a)E(X) b) P(X=7) c) P(X=10)

a) E(X) = average = 10
.........
P(x = 7) = poissonpdf(10,7)= .09 0r 9%
.........
P(x = 10)= poissonpdf(10,10)= .1251 0r 12.51%
