Homework Answers

Answer #1

20 black, 15 blue, 12 gray, 18 white and 10 brown

a) 6 of the same color: In such questions we take the worst case possible to make sure we have the required results guaranteed. We need 6 of the same color so we assume that we get 5-5 of each color first (that's the worst case) and as soon as we picked the next one we will have 6 of the same color.

So, total socks = 5*5 + 1 = 26

b) 6 gray socks: Again worst case is we get all the other socks then we are getting 6th gray at the end.

So, total socks = 20 + 15 + 18 + 10 + 6 = 69

These are the answer. Please comment if any doubt. Thank you.
