Number of cards in a deck =52 Number of cards that are spade =13 Number of cards that are eight =4 Number of cards that are spade and eight =1 Probability that the card drawn is a spade or an eight = 13/52+4/52 -1/52 =16/52 or 4/13
Number of cards in a deck = 52 Number of cards that are spade = 13 Number of cards that are heart = 13 Probability that the card drawn is a spade and heart = 13/52 + 13/52 = 26/52 or 1/2
