In this problem we have anne likes bill and george, bill and george.
00:23
Diana likes bill and larry, bill and second is larry.
00:42

Now total boys equals to, now total boys, boys which is equals to 5.
02:13
And total girls which is equals to 5 so we want to pair each way we want to pair each boy with each boy with which is equal to 5 c 2 5 combination of 2 so two different girls with each boys with 2 girls which is equal to 5 c by 5 c 2 so we can solve this we get 5 factorial, 2 factorial, 5 minus 3, 5 minus 2 factorial.
03:07
So we get 5 factorial, 2 factorial and 3 factorial.
03:17
Now solve this equation we get 5 4 into 3 factorial upon 2 factorial 3 factorial...
