Question

If you have 3 quarters, 5 dimes, and 2 nickels in your

Answer 1

Answer:

1/15

Step-by-step explanation:

The two events are not dependent so we can not use multiplication rule.

So P(getting a quarter on the first try) is

$\frac{3}{10}$

Assuming we get a quarter, we would be left with 9 coins, and only 2 quarters, so

P(getting a quarter second time in a row)

$\frac{2}{9}$

Multiply the two

$\frac{3}{10} \times \frac{2}{9} = \frac{6}{90} = \frac{1}{15}$
