<PRE><B>Question 308720</B>
A new sports car model has defective brakes 15 percent of the time and a defective steering mechanism 5 percent of the time. 
----------------------
Let’s assume (and hope) that these problems occur independently. If one or the other of these problems is present, the car is called a “lemon.” If both of these problems are present, the car is a “hazard.” Your instructor purchased one of these cars yesterday. What is the probability it is:
----------------------
P(2 defects) = 0.15*0.05 = 0.0075
P(no defects)= 0.85*0.95 = 0.8075
P(one defect) = 1 - [0.8075+0.0075] = 0.1850
------
a. A lemon? ::::0.1850
b. A hazard?::::0.0075
