Question

Taylor has a box that contains 3 pennies, 5 nickels, and 2 quarters. If she chooses a coin out of the box without looking, and then without replacing it draws a second coin, what is the probability that both coins will be quarters?

Answer 1

1/45

Explanation:

There is 10 total coins and only 2 are quarters so that's 2/10 but one is taken out so now its 1/9 because we think its a quarter. Multiply 2/10 x 1/9 and you get 2/90 simplify it and you get 1/45
