Ans. (0.8 * 0.8 = 0.64)

2. What is the probability that Earl will have to take out the garbage but will not need to wash the dishes

Ans.( 0.8 * 0.2 = 0.16)

Explanation:

Therefore the probability that Earl will have to do both chores is 0.8 * 0.8 = 0.64

2.The probability that Earl will have to take out the garbage but not need to wash the dishes

0.8 * 0.2 = 0.16
