There are 13 hearts and 52 total cards so 13/52 • 12/51 • 11/50

Assuming cards are drawn one afters the other without replacement

[ 1 / 4 ] [ 12 / 51] [ 11 / 50 ] = 132 / 10200

132 / 10200 = 11 / 850

13/52 x 12/51 x 11/50 = 1716/132600 = 0.012941176

That's roughly a 1.29% chance

13/52 x 12/51 x 11/50

.25 x .235 x .22

.012925
