Question

There are 10 pairs of socks in a cupboard from which 4 individual socks are picked at random. The probability that there is at least one pair is. (a) 195 323 (b) 99 323 (c) 198 323 (d) 185 323

Answer 1

$\huge{\underline {\underline {\green{Answer}}}}$

probability is 1-p(drawing four socks which ar different)

p(drawing four socks different) (20/20)*(18/19)*(16/18)*(14/17)

=>224/323

=>224/323so probability is 1-224/323

=>99/323

=>99/323option b
