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 blue? A. 30% B. 0.25 C. 3 D. 0.33
The answer is 1/3. Add up the number of socks : 4+5+3 =12 You want to find the probability of the blue socks, so that's 4/12, which can be simplified by dividing by 4, giving you 1/3 (.33) So the Answer is D.
