Question

DeAnna has 4 quarters, 3 dimes, and 3 nickels in her purse. She reaches into her purse and randomly grabs two coins, one at a time. What is the probability DeAnna will first grab a quarter and then, without replacing it, grab a nickel?

Answer 1

Your answer would be 1/10

Explanation:

step 1: 3/10 * 3/9

step 2: simplify these to get 1/10

Answer 2

For the first quarter the prob is 4/10, then without replacement to find a nickel you would multiply 4/10 by 3/9 which would give you .13333.
