Probability Review

The spinner was spun and 12 times out of 20 it landed on a multiple of 2. What is the experimental probability of landing on a section that is a multiple of 2?

What is the theoretical probability of landing on an even number?

The theoretical probability for an event is one-fifth. After 25 trials the experimental probability is one half. If you ran 2,000 more trials, what would you expect to happen?

• Theoretical probability increase and approaches one fifth

• Experimental probability increases and approaches one half

• Theoretical probability decreases and approaches one half.

• Experimental probability decreases and approaches one fifth
