P(Heads) = 44 heads in 70 tosses = 44/70 = 22/35
5. Note...that if Teesha is not considered for selection...the probability of selecting any other person first is 38/39 and the probability of selecting a second person ( but not Teesha) is 37/38
So....the total probability is 38/39 * 37/38 = (38/38) * (37/39) = 1 * 37/39 = 37/39
