Battery tests for the iPad Mini showed a mean life of 10.25 hours (the Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours. a. Give a mathematical expression for the probability density function of battery life. b. what is the probability that the battery life for an iPad Mini will be 10 hours or less
