using the file calculate the following: A. The probability that a new born will still be alive at age 70. B. Suppose A and B are two new born male babies who are unrelated to each other and their lives are independent of each other, what is the probability that both will be alive at age 70? C. Suppose A and B are two new born male babies who are unrelated to each other and their lives are independent of each other, what is the probability that both will be dead by age 70? D. Suppose A and B are two new born male babies who are unrelated to each other and their lives are independent of each other, what is the probability that at least A or B will survive to age 70?
