Lia Ewing · Answer 1

5 pairs of black socks*2 because it’s a pair = 10 socks

4 pairs of grey socks*2=8

2 pairs of white socks*2=4

1 pair of brown socks*2=2

1 pair of blue socks*2=2

10 socks+8 socks+4 socks+2 socks + 2 socks=26 socks in total

26/2=13+1 because you need to be sure you get one pair of socks. The smallest amount of socks you would have to grab to get at least one matching pair is 14 socks.
