Question

3. In his collection, Marco has 5 large gold coins, 12 large silver coins, 15 small gold coins, and 3 small silver coins. If he randomly picks a coin, what is the
probability that it is gold, given that it is small?

3/4
5/6
3/7
18/35

Answer 1

5/6

Since it is given that it is small, only worry about the small coins.

There are 18 total small coins and 15 of them are gold so 15/18 is the probability or when simplified = 5/6
