He usually waits on about 40 parties over a weekend of work. a) Estimate the probability that he will earn at least $450. b) How much does he earn on the best 1% of such weekends? a) P(tips from 40 parties > $450) = (Round to four decimal places as needed.) BEXERS b) The total amount that he earns on the best 1% of such weekends is at least S (Round to two decimal places as needed.).
