In a reliability context a randomly selected electronic component will undergo an accelerated failure time test. Let X1 take the value 1 if the component lasts less than 50 hours and zero otherwise, and X2 take the value 1 if the component lasts between 50 and 90 hours and zero otherwise. The probabilities that a randomly selected component will last less than 50 hours, between 50 and 90 hours, and more than 90 hours are 0.2, 0.5, and 0.3, respectively. Find ρX1,X2
