MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Example 2.34 It is known that 40% of a certain company's washing machines require service while under warranty, whereas only 10% of its dryers need such service. If someone purchases both a washer and a dryer made by this company, what is the probability that both machines need warranty service? Let A denote the event that the washer needs service while under warranty, and let B be defined analogously for the dryer. Then P(A) = and P(B) = Assuming that the two machines function ---Select--- of one another, the desired probability is P(A n B) = P(A) . P(B) = (0.40)(0.10) = Need Help?
