For the 1st card, there are ways to get a heart
so P(H[1]) =
For the 2nd card, there are ways to NOT get a heart
so P(X[2]) =
For the 3rd card, there are ways to NOT get a heart
so P(x[3]) =
For the 4th card, there are ways to get a heart
so P(H[4]) =
--------------------------
You want all of these, so multiply probabilities
Definitely get a 2nd opinion on this!!
