Question 1042727
A drawer contains a mixture of 12 black socks, 
8 white socks, and 4 red socks. You randomly 
select 2 socks to wear. Determine the 
probability that both are black. (Give your 
answer as a fraction.)
<pre><b>
That's 

"12 black socks Choose 2", or 12C2 ways 

out of 

"24 possible socks Choose 2", or 24C2 ways.

So we have:

{{{(12C2)/(24C2)}}}{{{""=""}}}{{{66/276}}}{{{""=""}}}{{{11/46}}}
