Question

A drawer contains 4 pairs of blue socks, 5 pairs of white socks, and 3 pairs of gray socks. If a pair of socks is randomly chosen, what is the probability it is gray?

A) 30%

B) 0.3

C) 0.25

D) 3

Answer 1

C) 0.25

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

There are 4+5+3 = 12 socks.

Of those, 3 are are gray.

3/12 = 0.25.

So the correct answer is:

C) 0.25

Answer 2

Answer: 0.25

Explanation:

Number of pairs of blue socks = 4

Number of pairs of white socks = 5

Number of pairs of gray socks = 3

Total pairs of socks= 4 + 5 + 3 = 12

Probability of choosing gray socks will be the number of gray socks divided by the total number of pairs of socks. This will be:

P( choosing gray) = 3/12

= 0.25
