The lifespan of lions in a particular zoo are normally distributed. The average lion lives 10 years; the standard deviation is 1.4 years. Use the empirical rule (68-95-99.7) to estimate the probability of a lion living less that 7.2 years. I need an answer that provides detailed how each number of percentage was accumulated. The answer is suppose to be 2.5% but there is not explanation of how the answer is 2.5%
