Question

Jim has some socks in two drawers. In one drawer he has 3 red and 6 green socks. In the other drawer he has 2 red and 2 green socks. If jim takes one sock out of each drawer, how probable is it that both will be red?

Answer 1

5/6

Explanation:

There are 5 steps to solving this problem:

• Calculate the number of marbles in each drawer
• Calculate the fractional number of red marbles in each drawer
• The answer is the number of red marbles in both drawers added together.

Using these steps, we see that:

1. 9 in the first drawer and 4 in the other drawer
2. 3/9 or 1/3 of the socks in the first drawer are red, and 1/2 of the socks in the second drawer are red
3. Adding 1/3 and 1/2 together equals 5/6
4. Therefore, the answer is 5/6!
