1 Thursday we talked about the probability and probability m

1) Thursday we talked about the probability and probability models. We also looked at an example that described the possible outcomes of rolling two die. Write the possible outcomes. Then write a probability statement for rolling a 1 up to 12, separately. Do they form a probability model?

2) Using the data found in exercise 1, answer the following (write them as a probability statement)

a.What is the probability of rolling a 7 and one die is at least a 2?

b. What is the probability of rolling a 5 or 10?

c. What is the probability of rolling a 7 or one die is a 2?

3) The probability model below is missing a value.   Fill in the missing value.

a. What is the probability X is at least a 3 (write as a probability statement)?

b. What is the probability that X is less than 3 (write as a probability statement)?
