A board is made up of 16 squares. Each square can only fit one coin. The four squares in the center of the board are gray and the rest is white. Malcolm randomly tosses a coin blindfolded. Without removing the first coin, he tosses another coin. Given that both coins land in the squares on the board, find the probability that the first coin lands on a white square and the second coin lands on a gray square. Also, find the probability that both coins land on gray squares.

Bonnie and Connie are twins with identical purses. Bonnie needs 35 cents to pay for a parking meter. Suppose that Bonnie's purse has 5 quarters, 3 dimes, and 2 nickels while Connie's purse has 2 quarters, 5 dimes, and 3 nickels in it. Not being able to tell the difference between the purses, Connie picks one at random and grabs two coins from it.
