The Fibonacci sequence works like this. Take the first two generations, add them together and that gives you the third. Add the second and third to get the fourth. Add the fourth and fifth to get the sixth.
So you need to add the sixth and seventh to get the eighth.
13 + 21= 34
Add the seventh and eighth to get the ninth.
21 + 34= 55
Answer is C- 34, 55
We can approach this as how many 2 person female committees can we make that we can add the male to.
5 C 2 (combinations of 5 taken 2 at a time order doesn't matter)
<u>5 x 4</u> = <u>20</u> = 10 ways. Since the male can join any of the groups there are
2 x 1 2 still 10 ways.
<u>
</u>Here's another way of looking at it. Let's call the five females A, B, C, D and E
<u>
</u>Here are the pairings:
<u />AB BC CD DE
AC BD CE
AD BE
AE The male can be the 3rd person in any group. Once
again, there are 10 ways to do this.
