Question

There are 18 black socks and 12 navy socks in your drawer. The room is dark and you can't turn on the light. What is the least number of socks that you have to take you of the drawer to be certain that you have a pair of the same color? The solution is a number.

Answer 1

9514 1404 393

Answer:

3

Explanation:

The largest number you can take without having a pair is the number of colors, 2. One more sock must match one already in hand.

You must take one more than the number of colors:

2 + 1 = 3

You must take 3 socks to be certain of a pair the same color.
