1) Suppose that in basketball you are successful on 77% of your free throw attempts. You take 15 free throws. Round your answers to three decimals if needed. a. How many of the attempts do you expect will be successful? b. What is the probability that you will make between (inclusive) 10 and 12 free throws? c. What is the probability that you make all your attempts?

2) Suppose that 5% of a population carries antibodies to a virus. For a research project, you need 7 people with antibodies to the virus. How many people must you test to be 95% certain of getting at least 7 people with the antibodies? This problem will need some trial and error...you are trying to find n so that P(X7)=0.95
