A recent study found that the average life expectancy of a person living in Africa is 53 years with a population standard deviation of 7.5 years. If a person in Africa is selected at random, what is the probability that the person will die before the age of 65? Assume that life-expectancy is normally distributed. Shade the desired region and find the corresponding probability.
