Question 653377
<font face="Times New Roman" size="+2">


I don't know where you got the idea that you needed to use permutations -- If the two boys are Bobby and Billy that would be the same as if they were Billy and Bobby, right?


You need the number of <b><i>combinations</i></b> of 6 boys taken 2 (NOT 5) at a time times the number of combinations of 4 girls taken 3 at a time.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ {{6}\choose{2}}\ \times\ {{4}\choose{3}}\ =\ \frac{6!}{4!2!}\ \times\ \frac{4!}{3!1!}\ =\ \frac{6\times5}{2}\ \times\ 4]

My calculator said it, I believe it, that settles it
