The probability that a person owns a microwave oven is .75, that a person owns a compact disk player is .25, and that a person owns both a microwave and a CD player is .16. Find the probability that a person owns either a microwave or a CD player, but not both.

Answer 1

0.75+0.25-0.16=0.84

Answer 2

p(not having both)=0.84
=0.84-0.16
=0.68
