1) The Total cards in the deck 52
4 x 13 =52
2) The Probability of selecting any red card
Since there are only two colors in the whole deck, black and red.
P (red) = 26/52 =1/2
3) Find the probability of randomly selecting a card that is a 3 of SPADE or 10 of hearts card?
Probability 3 of Spade U Probability of 10 hearts = P(3 spade) + P (10 Hearts)
P (3 of spade) = 1/52
P (10 of Hearts) =1/52
P = 2/52 =1/26
