Thursday we talked about the probability and probability mod

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?

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

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

What is the probability of rolling a 5 or 10?

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

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

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

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

Answer: Similar example..I HOPE IT HELPS YOU

A television manufacturer has kept data on all televisions it has sold during the past decade to determine how many complete years of service the TV gave before it had to be brought in for repairs. Here is their data: Years % of televisions 0 - 12%, 1 - 26%, 2 - 33%, 3 - 14%, 4 - 9%, 5 or more 6% Notice that the very form in which the data is tabulated forces us to view the sample space in a particular way. For the data as presented, the natural sample space is S = {0, 1, 2, 3, 4, 5 or more}. The sample space shows six possibilities because that
