**Post I (Binomial Probability)**

1. Choose a value for p between 0.20 and 0.80. It should have at least two decimal places. When you create the thread on Blackboard, put your p = your value in the title. I must be different from the other student’s p.

2. Find the following binomial probabilities. Show all your work. Round to 4 decimal places.

a. Find the probability that exactly 6 of 25 are successes.

b. Find the probability that at least 10 of 25 are successes.

c. Find the probability that at most 5 of 25 are successes.

d. Find the probability that there are between 3 and 7 successes, inclusive.

**Post 2 (Normal Probability)**

1. Choose a classmate’s Post 1 that has not been done already and check their work. Check carefully because if you miss a mistake you will lose points.

2. Use the information that you need from Post 1. Then, if possible, find the **normal approximation** for each of the probabilities as we learned in **section 5.5** in the textbook. Show all your work. Round to 4 decimal places.

a. Find the probability that exactly 6 of 25 are successes.

b. Find the probability that at least 10 of 25 are successes.

c. Find the probability that at most 5 of 25 are successes.

d. Find the probability that there are between 3 and 7 successes, inclusive.

**Post 3**

1. Choose a classmate’s Post 2 that has not been done already. Check the work in Post 1 and Post 2. Check carefully because if you miss a mistake you will lose points.

2. Compare the probabilities in Post 1 with the probabilities in Post 2. Write at least 3 sentences explain the differences and similarities in the binomial distribution and the normal distribution.
