You can put this solution on YOUR website! One card is drawn from a standard deck of cards. What is the probability that card is a heart, given that the card is red?
P(heart | red) = P(heart and red)/P(red) = (13/52)/(26/52) = 13/26 = 1/2

One card is drawn from a standard deck of cards. What is the probability that card is a jack, given that the card is red?
P(jack | red) = P(jack and red)/P(red) = (2/52)/(26/52) = 2/26 = 1/13
