Answer:

P(2 quarters) = 19/ (13*16) = 19/208  = 0.0913

Step-by-step explanation:

probability of getting 2 quarters?

ok

first draw:  there are 20 quarters to choose from

second draw: there are 19 quarters left to choose

so Total coins are 65 coins

P(2 quarters) = P( 1st quarter)* P(2nd quarter)

P(2 quarters) =  20/65   *   (19/64)

P(2 quarters) = 4/13 *  19/64

P(2 quarters) = 19/ (13*16) = 19/208
