Question 1114788
<br>
(1) It is NOT a permutation; on a committee the order is NOT important.<br>
(2) For each of the ways of choosing 3 of the 12 girls there are many ways of choosing 2 of the 10 boys.  That "for each" means you need to multiply the two numbers together -- not add them.<br>
Fix those two parts of your analysis of the problem and you should reach answer d.
