[P(3,2) + P(7,2)]/P(10,4)= 48/5040

P(3,2) because there 3 people and you just need 2. P(7,2) is the other random people who shouldn't be part of 3 peeps who are more than five years. We add because they are both requirements... P(10,4) because 10 taken 4

I hope its correct... Please tell me if it is...
