There are 3 nickelss, 2 dimes, and 5 quauters in a purse. Three coins are selected in succession at rondom. Find the probabililty.
1. P(nickel, then dime, then quater), if replacement occurs.
2. P(3 dimes), if replcement occurs.
P(nickel, dime quarter) = (3/10)(2/10)(5/10) = 30/1000 = 3/100 = .03
P(3 dimes) = (2/10)(2/10)(2/10) = 8/1000 = ..008
