1. Calculating Binomial Probability Exactly – Binompdf At most – Binomcdf At least - “1 – “

2. Exactly X = # blood donor s 012345678 P(x) Records at a local blood bank show that in any year about 20% of the population donate blood. There are 8 people in line at a checkout. What is the probability that 5 people are donors? Binompdf(8,.20, 5)

3. At Most/Less than Records at a local blood bank show that in any year about 20% of the population donate blood. There are 8 people in line at a checkout. What is the probability that at most 3 people are donors? X = # blood donor s 012345678 P(x) Binomcdf(8,.20, 3)

4. At Least/More than Records at a local blood bank show that in any year about 20% of the population donate blood. There are 8 people in line at a checkout. What is the probability that at least 2 people are donors? X = # blood donor s 012345678 P(x) 1 - Binomcdf(8,.20, 1)
