Three cards are drawn at random from a standard deck of cards, without replacement. Find the probability that the suits of the cards are spades, hearts, spades, in that order.

The probability is 13/52*12/51*11/50 = 11/850.

There is this

 

13/52 for spades

13/51 for hearts

12/50 for spades

 

Since one is removed we have 51 cards for the next, 50 for the 3rd

 

Multiply them.

That's right since I got 13/850 and he got 2028/132600 which is the same
