Of all mortgage foreclosures in the United States, 43% are
caused by disability. People who are injured or ill cannot
work–they then lose their jobs and thus their incomes. With no
income, they cannot make their mortgage payment and the bank
forecloses. 17 mortgage foreclosures are audited by a large lending
institution. (Give your answers correct to three decimal places.)
(a) Find the probability of P(Five or fewer of the foreclosures are
due to disability)
(b) Find the probability of P(At least three
foreclosures are due to a disability)
