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
