There are 30 socks in a bag. 30% is in blue color. What is the probability to take two blue socks?
Choose one:
A) 11/145
B) 12/145
C) 13/145
D) 14/145
E) 22/145
out of 30% 30 socks are blue =&gt; out of 30 9 socks are blue in color.   probability of selecting two blue socks out of 9 socks is 9C2.   so the required answer is :   (probability of selecting two blue socks out of 9 socks) /(Probability of selecting 2 socks out of 30 socks)   =&gt; (9C2) / (30C2)   =&gt; 36 / 435   =&gt; 12/145   ANSWER:12/145
