4) Your Conditional Sample Space should only have those points where at least 2 Heads come up Heads. The probabilities of the points in the Conditional Sample Space {(H,H,H,H), (H,H,H,T), etc} where order matters is 1/11 since there are 11 points in this sample space. The Probability of the Event that there are exactly 2 heads is 6/11 since there are 6 points in the
