- The random variable & has the probability density function 0, fe(7) = { 7(3x - a*), %3D a). Find the constant y and cumulative distribution function of the E. b). Find the probability that the & will be less than 10 and greater then 1. c). Find mean value and standard deviation of the E.arrow_forwardBattery life between charges for the Motorolla Droid Razr Maxx is 20 hours when the primary use is talk time. The battery life drops to 7 hours when the phone is primarily used for Internel applications over cellular. Assume that the battery life in both cases follows an exponential distribution. a. Show the probability density function for battery life for the Droid Razr Maxx phone when its primary use is talk time. b. What is the probability that the battery charge for a randomly selected Droid Razr maxx phone will last no more than 15 hours when its primary use is talk time? c. What is the probability that the battery charge for a randomly selected Droid Razr Maxx phone will last more than 20 hours when its primary use is talk time? d.
