sample space is all the combinations the could occur { [hn, hd, hp],etc, etc }
Each outcome is equally likely, and there are 8 of them. So p(hn,hd,hp)= 1/8th

All outcomes are equally likely and they each have a probability of 1/8. Since there is only one outcome containing 3 heads, the probability is 1/8
