1. You roll a number cube numbered one to six 12 times. P(5) = . What type of probability is illustrated and why?
(1 point)
experimental; the result is based on the number of possible outcomes
experimental; the result is found by repeating an experiment
theoretical; the result is based on the number of possible outcomes
theoretical; the result is found by repeating an experiment
2. A jar contains blue, red, yellow, and green marbles. P(blue) = . What type of probability is illustrated and why?
(1 point)
experimental; the result is based on the number of possible outcomes
experimental; the result is found by repeating an experiment
theoretical; the result is based on the number of possible outcomes
theoretical; the result is found by repeating an experiment
theoretical; the result is based on the number of possible outcomes, as the probability is based on the ratio of blue marbles to the total number of marbles in the jar.

theoretical; the result is found by repeating an experiment
theoretical; the result is based on the number of possible outcomes, as the probability is based on the theoretical likelihood of rolling a 5 on a fair 6-sided die. The experiment is being repeated to gather data and confirm the accuracy of the theoretical probability.

theoretical; the result is based on the number of possible outcomes
theoretical; the result is found by repeating an experiment
theoretical; the result is based on the number of possible outcomes, as the probability is based on the theoretical likelihood of selecting a blue marble from the jar based on the ratio of blue marbles to the total number of marbles in the jar. No experiment is being repeated to determine the probability in this case, it is calculated based on the theoretical concept of probability.
A number cube is rolled 160 times. The number 2 comes up 39 times. What is the experimental probability of rolling a 2? What is the theoretical probability of rolling a 2?
(1 point)
39/160:1/80
The experimental probability of rolling a 2 is 39/160.
The theoretical probability of rolling a 2 on a fair number cube is 1/6, or approximately 0.1667.
A spinner is divided into 11 equal sections numbered from 0 to 10. You spin the spinner once.
What is P(even)?
There are 6 even numbers (0, 2, 4, 6, 8, 10) out of a total of 11 possible outcomes on the spinner.
Therefore, the probability of spinning an even number is:
P(even) = number of even outcomes / total number of outcomes
P(even) = 6 / 11
So, the probability of spinning an even number is 6/11.
