    there are only two possible outcomes , either the card is a heart or it ain't . the probability is one in two .

    P = 1/2 half of red cards are hearts

    given that the card is red? So you only have two red suits Chance of a heart is 1/2 or 50%

    P(heart|red) = P(Red Heart Card) / P(Red card) = (13/52)/(26/52) = 13/26 = 0.5 or 50%
