A.What is the probability of drawing a red card
B.What is the probability of drawing a queen
c. What is the probability of drawing a red queen.
d. What is the probability of drawing a queen given that you drew a face card (face card are jacks, queens, and kings).

A. 26/52 = ?
B. How many queens are there? Divide by 52.
C. How many red queens are there? Divide by 52.
D. If the face card was replaced, no different from B.
If not replaced, and queen drawn, 3/51. Or if queen not drawn, 4/51.
Eitheror probabilities are found by adding the individual probabilities.
