A : The event that the card drawn is an ace
H : The event that the card drawn is a heart
S : The event that the card drawn is a spade

A : The event that the card drawn is an ace
H : The event that the card drawn is a heart
S : The event that the card drawn is a spade
then which of the following holds ?
Options
A.9P(A) = 4P(H)
B.P(S) = 4P(A ∩ H)
C.4P(H) = 3P(A υS)
D.P(H) = 9P(A ∩ S)
Solution
After removing face cards & tens remaning cards = 52 - 16 = 36
P(A) =
, P(H) = 
, P(S) = 
P(A ∩ S) =
P(A ∩ H) =
P(A υ S) =
P(A) =
, P(H) = , P(S) = P(A ∩ S) =
P(A ∩ H) =
P(A υ S) =
