52 Playing Cards in a Pack
P(Heart) = 13/52 P(King) = 4/52 P(Heart and a king)= 1/52 P(Heart or a king)=P(Heart) + P(King) - P(Heart and a king) =13/52+4/52-1/52 =16/52
aces in card=4 P(Aces)=4/52 clubs are= 13 P(Club) = 13/52 P(An Ace or a Club)= P(Ace). P (club)= 4/52*13/52=1/52
P(Card is King) = 4/52 P(Card is Queen) = 4/52 Since these are mutually exclusive events.i.e. they can't happen in a single trial these two probabilities will be added. P(King or Queen) = 4/52 + 4/52 = 8/52
p
P(Heart or Club) = P(H) + P(C) = 13/52 + 13/52 = 26/52 = 1/2 = 0.5.

P(Heart) = 13/52 P(King) = 4/52 P(Heart and a king)= 1/52 P(Heart or a king)=P(Heart) + P(King) - P(Heart and a king) =13/52+4/52-1/52 =16/52
aces in card=4 P(Aces)=4/52 clubs are= 13 P(Club) = 13/52 P(An Ace or a Club)= P(Ace). P (club)= 4/52*13/52=1/52
Probability (P) of A or B is: P(A) + P(B) - P(A and B). Apply to the question is: P(Q) + P(Club) - P (Q&Club) = 4/52 + 13/52 - 1/52 = 16/52 = 4/13 or .3077 or 30.77%.
drawing a club total club =13 P(Club)= 13/52 drawing a 7 total 7 = 4 P(7) = 4/52 P(a club and a 7) = P(Club) + P(7) as events are mutualy exculisve P(a club and a 7) = 13/52+4/52 P(a club and a 7) = 17/52

The probability of A is denoted P(A) and the probability of B is denoted P(B). P(A or B) = P(A) + P(B) - P(A and B). Say P(A) = Probability of drawing a heart, which is 13/52. Say P(B) = Probability of drawing a three, which is 4/52. We now have to determine P(A and B) which is the probability of a heart and a three, which is 1/52. We now can determine the probability of drawing a heart or a three which is 13/52 + 4/52 - 1/52 = 16/52 = 4/13.
Let A= drawing a ten B= drawing a heart P(A or B) = P(A) + P(B) - P(A & B) A & B denotes a ten of hearts. P( ten or a heart)= 4/52 + 13/52 -1/52 =16/52 = 4/13

P(at least one heart out of two cards drawn) = 1 - P(neither being a heart) = 1 - (39/52)(38/51) = 1 - (2 * 3 * 13 * 19)/(2 * 2 * 3 * 13 * 17) = 1 - 19/34 = (34 - 19)/34 = 15/34 P(at least one heart out of two cards drawn) = 15/34
