There were 8 socks of white, green and blue shuffled in a draw. The probability of selecting a white sock is 1/4. What is the probability of selecting a green sock if the probability of selecting the yellow sock is 5/8?

P(select green sock) = 1/8

Step-by-step explanation:

If the probability of selecting a white sock is 1/4, then we know there are 2 white socks:  1/4 has the same value as 2 out of 8.

Similarly, we can determine the number of yellow socks:  5/8 is equivalent to 5 out of 8.

Thus, 2 socks are white; 5 are yellow; and the last (the 8th) sock is green.

P(select green sock) = 1/8
