There are 10 pair of socks in a cupboard from which 4 individual socks are picked at random. The probability that there is at least one pair is: Choose the correct choice from the following answers
A) 195/323 B) 99/323 C) 198/323 D) 185/323 E) 115/323
probability is 1-p(drawing four socks which ar different)   p(drawing four socks different) (20/20)*(18/19)*(16/18)*(14/17)=&gt;224/323   so probability is 1-224/323=&gt;99/323   ANSWER:99/323
