Question

59. A man has 53 socks in his drawer : 21 identical blue, 15 identical black and 17 identical red. The lights

are turned off and he is completely in the dark. At least how many socks must he take out to make

100 per cent certain that he has two black socks ?

(A) 15 (B) 26 (C) 39 (D) 40

Answer 1

(D) 40 as black socks are not visible in dark and the person only wore two black socks and the peraon can't find 13 socks of black colour
Therefore 21+17+(15-13)
= 21+17+2
= 40
