Adrawer holds 6 white socks, 8 black socks, and 4 blue socks. if a sock is pulled from the drawer randomly, what is the probability that it will not be a blue sock?
a. 2 over 9
b. 1 over 7
c. 5 over 7
d. 7 over 9

There are a total of 18 socks from the drawer. Out of this number, there are 14 that are not blue. The probability of not picking a blue sock is the quotient when 14 non-blue socks is divided by 18 total number of socks. Therefore, the answer is 14/18 which is equal to 7/9. Thus, the answer is letter D.
