standard deck of cards

Question

find the probability of drawing a face card or a diamond from a standard deck of cards

Answer 1

P(F) = 3/13= 12/52

P(D) = 1/4 13/52

P(F^D) = 3/52

P(FvD) = P(F) + P(D) - P(F^D) = 3/13 + 1/4 - 3/52

= (12+13-3)/52 = 22/52

= 11/26 = probability of getting either a face card or a diamond
