Question 697712
Your drawer contains 8 red socks and 9 blue socks.  It’s too dark to see which are which, but you grab two anyway.  What is the probability that you get one of each color?
<pre>
There are C(8,2) ways to get two red socks and C(9,2) ways to get two
blue socks.

That C(8,2)+C(9,2) = 28+36 = 64 ways to succeed.

There are C(17,2) = 136 ways to get any two socks.

So the probability is 64 out of 136 or {{{64/136}}} which
reduces to {{{8/17}}}
