Question

Norma has 10 black,12 white,and 3 brown pairs of socks in one drawer. What is the probability that without looking, Norma will pick a BROWN pair of socks from the drawer?

Answer 1

Ok so the answer to this question would be 3/25

Explanation:

The answer to the probability is always a fraction

The numerator is the number of favorable outcomes - in this problem, it is the brown socks

The denominator is the total amount of possible outcomes - in this problem, it is the total amount of socks

3/ 10+ 12 +3 = 3/25

- By the way, have your answer in simplest form - always

Answer 2

1/100.

Explanation:

Total number of socks in the drawer

= 25.

Prob(First pick is brown) = 3/25.

Prob(Second pick is brown) = 2/24 = 1/12.

So the required probability

= 3/25 * 1/12

= 3/300

= 1/100.
