Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
Probability of a heart is 1/4
Probability of a face card is 3 cards in 4 suits or 12/52 or 3/13.
Probability of a heart intersecting with face card is 3 hearts/12 cards or 1/4
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!

A = set of hearts
B = set of face cards
A intersect B = set of hearts AND face cards = set of face cards that are hearts

P(A intersect B) = (number of face cards that are hearts)/(number of cards total)
P(A intersect B) = 3/52
