Suppose from a pack of 52 cards one is drawn at random what is the probability that it is either an ace or a red.

A={event has ace}R={event has red}P(A)=4/52 ,P(R)=26/52P(A∩R)=2/52∴P(A∪R)=P(A)+P(R)-P(A∩R)=4/52+26/52-2/52=28/52

P(A)=4/52 ,P(R)=26/52

P(A∩R)=2/52

∴P(A∪R)=P(A)+P(R)-P(A∩R)=4/52+26/52-2/52=28/52
