Purpose: This week you will use a technology program to obtain Binomial Probabilities

Post: This week you will use some form of technology, either Excel or a TI83/84 Plus to determine the probability of an event.

According to the National Center for Health Statistics in Vital Statistics of the US, there is roughly an 80% chance that a person of age 20 years will be alive at the age of 65. Suppose that 3 people of age 20 are selected at random. Find the probability that exactly 2 of them will still be alive at age 65. Use the steps below and the screenshots on page 247 in your e-text for help. When you are finished, post a picture of your work and leave a question for your classmates to answer. Your question should be the same percents and the same ages, but change the last question. (For instance: Suppose that 12 people of age 20 are selected at random. Find the probability that exactly 9 of them are still alive at 65.)
