  1. 5 of C = 1/52
    5 = 4/52 =1/13
    club = 1/4 = 13/52
    jack = 4/52 =1/13
    spade same as club
    J of S, same as 5 of C
    You only took one card. It can not be 5 and jack
    five or jack 1/13 + 1/13 = 2/13
    heart and jack is jack of hearts 1/52
    Heart OR jack
    draw Venn diagram
    There are 13 hearts
    There are 4 jacks, three of which are not hearts. The jack of hearts is the intersection of the sets, careful not to count it twice.
    So out of the 52 cards
    13 are Hearts and 3 more are jacks that are not hearts
    total = 13+3 = 16
    so
    16/52 = 4/13

    heart or jack = 1/4 + 3/52
