11 cards numbered 11 through 21 are placed in a box. A card is removed at random from the box. Find the probability that the number on the card is either even or divisible by 3.

even: 12, 14, 16, 18, 20

divisible by 3: 12, 15, 18, 21

overlap: 12, 18

P(even)+P(divisible by 3)-P(overlap)=(5/11)+(4/11)-(2/11)=7/11
