The average life span of a phone battery is 21 months with a standard deviation of 1 months. Assuming the battery life is normally distributed, what is the probability that a battery chosen at random will last more than 24 months? Note: When finding Z-score round it to two decimal places and then use the Standard Normal Curve Table to find the area with four decimal places accuracy. Round the answer to four decimal places.
