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 n
umber 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.
1 answer:
9514 1404 393
Answer:
3
Step-by-step 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.
