Michelle draws a card from a standard deck of 52 cards. She replaces the card and draws a second card. What is the probability that she draws a Heart and then a Spade?

The probability of a heart is 13/52 and for a spade = 13/52. The probability of both events occurring is found by multiplying the probabilities of the individual events.
13/52 * 13/52 = ? 
First you must determine whether this is a permutation or combination problem.
*It is a permutation
Next, use the formula permutation formula and plug in your variables.Solve.
*nPk= n!/(nk)!
