A drawer holds 5 red hats and 5 blue hats. What is the probability of getting exactly three red hats or exactly three blue hats when taking out 6 hats randomly out of the drawer and returning each hat before taking out the next one?
[ "A)3/8", "B)1/4", "C)5/8", "D)5/16" ]

Let's find the probability of getting exactly 3 red hats. One possible case is red-red-red-blue-blue-blue. The probability of this is 1/2*1/2*1/2*1/2*1/2*1/2 = 1/64 There are 6C3 = 20 such cases so we need to multiply this by 20. P(exactly 3 red hats) = 20*1/64 = 5/16 Note that when we get exactly 3 red hats, then we a...

A girl has exactly 6 quarters, 7 dimes, and 10 nickels in her pocket. If she withdraws a number of these coins at random, how many coins would she have to withdraw to ensure that she has at least a 50 percent chance of withdrawing at least one quarter?
[ "A)1", "B)2", "C)3", "D)4" ]
C
When the probability of NOT drawing a quarter is 50% or less, then the probability of drawing a quarter is at least 50%. P(not drawing a quarter with 2 coins) = 17/23 * 16/22 = 136/253 > 50% P(not drawing a quarter with 3 coins) = 136/253 * 15/21 = 680/1771 < 50% The answer is C.
