Question

one card is selected from a standard deck of 52 cards. what is the probability that the card is either a club or jack?

Answer 1

Let A=card drawn is a club
B=card drawn is a jack .
\[P(A \cup~B)=P \left( A \right)+P \left( B \right)-P \left( A~intersection~B \right)\]
P(A)=13/52
P(B)=4/52
P( A intersection B)=1/52
find P(A U B)
