Hi I have been given this question:

Three cards are picked without replacement from a shuffled standard pack of 52 playing cards. What is the probability of picking an ace followed by 2 hearts?

My attempt: Let omega be a set of ordered sequences of 3 cards drawn without replacement

|omega|=52x51x50

Let A be the event of picking an ace followed by 2 hearts

A=(ace of hearts, heart, heart)+(ace but not ace of hearts, heart, heart)

How do I calculate |A|?

Thanks for your help
