7.124%, or 1 in 14
If you add 1 for the ace to 13 for Hearts cards you have 14 cards out of a 52 card pack. So the probability of selecting one of those 14 cards is 14/52 = 7/26 That is 0.2692307692307.........( recurring 69230) Correcting to 4 significant figures that equals 0.2692 which equals 26.92% That means that you will select a correct card in just over 1 in 4 times.
Prob(At least one ace in ten cards out of 52) = 1 - Prob(No aces in ten cards out of 52) When you start there are 48 non-ace cards out of 52, At the next draw, there are 47 non-ace cards out of 51, and so on = 1 - (48/52)*(47/51)* ... *(39/43) = 1 - 0.41 = 0.59
