n the following exercise you are to use the binomial probability formula to answer the question . Begin with the formula, and show substitution into the formula.
-Suppose you purchase a bundle of 10 bare-root broccoli plants. The sales clerk tells you that on average you can expect 5% of the plants to die before producing any brocolli. Assume that the bundle is a random sample of plants. Use the binomial formula to find the probability that you will lose at most 1 of the broccoli plants.

-In 1998, Mark Mcgwire of the st. Louis Cardinals hit 70 home runs, new record. Was this feat as surprising as most of us thought? In the 3 seasons before 1998, Mcgwire hit a home run in 11.6% of his times at bat. He went to bat 509 times in 1998. Mcgwires homerun count in 509 times at bas has approximately the binomial distribution with n=509 and p=0.116. What is the mean # of home runs he will hit in 509 times at bat? What is the probability of 70 or more home runs?
