In an ordinary deck there are 52 cards, 4 suits of 13 cards each and 12 face cards(3 face cards per suit)
:
Probability(P) of drawing a spade or face card = (13/52) +(12/52) -(3/52) = 22/52 = 11/26
:
Note We subtract the 3 spade face cards since they were already counted in 13/52
:
P of drawing a red card or face card = (26/52) +(12/52) -(6/52) = 32/52 = 8/13
