The life lengths of two transistors in an electroniccircuit is a random vector(X; Y ) where X is the life length of transistor 1 and Yis the life length oftransistor 2. The joint probability density function of(X; Y ) is given by| 2e-(x+2y)x 2 0, y 20fx,y(x,y) =fx.MX.v)elseThen the probability that the first transistor last for atleast half hour given that the second one lasts at leasthalf hour equalsSelect one:a. 0.3669b. 0.3935c. 0.7772d. 0.6318e. 0.606

The conditional probability is, P(A| B) = P( A n B) / P(B)
