25/100 or 0.25, or 25%
Trent has 30 marbles in a bag. The theoretical probability of choosing a green marble is 1/3. How many marbles are green?
10 green marbles

Describe the difference between events that are certain, likely, unlikely, or impossible.
Certain would be 100% of the time, likely is anything greater than 50% of the time, unlikely is anything less than 50% of the time, and impossible is anything that has a 0% chance of occuring.

Jarvonya spins a spinner with 5 equal sections numbered 1-5. What is the probability she will spin and land on a composite number?
What is 1/5 or 0.2, or 20%?
Hasaan has a spinner with 5 equal sections, each a different color. After only 10 spins, the pointer had landed on red 40% of the time. After a whopping 1,000 spins, the pointer landed on red only 22% of the time. How can Hasaan account for this change in experimental probability?
As the number of trials increase, the experimental probability reaches closer to the theoretical probability. (The Law of Large Numbers)
What date are we starting school at Morton next year?
