Question

probability question, help plz?

Answer 1

Firstly, do you know how to calculate the probability of >=2 heads, given >=3 tails?

Answer 2

I would just think of it as flipping 4 coins and hoping for 2 heads. I have to have 3 tails, so I'm left with only 4 chances to get a head, and I need 2 of them or more to work. So calculate P(2) + P(3) + P(4)
