Question

There are nine socks in a drawer, each a different color. In how many ways can you randomly draw 8 of them?

Answer 1

Note that the question is equivalent to "In how many ways can you leave one sock in the drawer" :)

Answer 2

Huh?

Answer 3

If you take eight of the socks out of the drawer, there will be only one left. So we can calculate either the combinations for the 8 socks we took or the combinations for the single sock we left.

Answer 4

Would it be
A. 8/9
B. 1
C. 8
D. 9

Answer 5

The sock left in the drawer can be of any colour. There are nine colours, so there are nine possibilities. Your answer is 9.

Answer 6
