1 f(t) e-y/30000 ,y> 0; 0, otherwise 30000 a. Suppose that I install two of these LED lights to make a double spotlight. Let Tmax represent the time to failure of the last bulb in the pair to burn out. We will assume that the times to failure are independent. For this random variable, Tmax, determine the cdf, Fmax(t), and using the cdf, determine fmax(t), the pdf. [5] b. Now, let Tmin represent the time to failure of the first bulb in the pair to burn out. Again, we will assume that the times to failure are independent. For this random variable, Tmin, determine the cdf, Fmin(t), and using the cdf, determine fmin(t), the pdf. [5] C. Find E(Tmin) and E(Tmax). [4] 1 f(t) e-y/30000 ,y> 0; 0, otherwise 30000 a.
