You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher.  What is the  P ( A ∪ B ) ?  Express your answer as a decimal and explain how you got your answer please.

set A = {2, 4, 6, 8, 10}   (only even cards)

set B = {8, 9, 10}    (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common. 

So the answer is: P(A ∩ B) = {8,10}
