Suppose that 97% of the population is not lactose intolerant. If you were to randomly select 3 people at random, what is the probability that all of them are not lactose intolerant? Assume that each selection is made with replacement. If you were to randomly select 3 people at random, what is the probability that at least one of them is lactose intolerant? Assume that each selection is made with replacement. If you were to randomly select 3 people at...

1.) Determine the probability that in a group of 3 people, none of them die from heart disease or cancer 2.) Determine the probability that in a group of 3 people, at least one of them die from heart disease or cancer, and explain why it is so difficult to calculate this probability directly yet so easy to calculate it using a trick. Odds of dying from Heart disease AND cancer are 1 in 7
