1. You draw one card from a deck of 52.

Question

b. What is the probability of drawing a heart if you know that you have drawn a 

    red card?

c. What is the probability of drawing a heart if you know that you have a face 

    card?

d. What is the probability of drawing a face card if you know that you have a 

    heart?

Answer 1

P(H/R) = 50% If it's red, there are only 2 alternatives, a heart or a diamond

P(H/F) = 25% It's one of 4 suits. 1/4 =25%

P(F/H) = 23.09% 3 face cards out of 13 possible cards = 3/13 =23.09% approximately
