Exploring Theoretical and Experimental Probability in 7th Grade Math

What does a probability of 0 indicate?

• 50% chance of happening

• Impossible to happen

• Unknown probability

• Certain to happen

What is the probability of rolling a 4 on a six-sided die?

• 1/6

• 1/4

• 1/2

• 1/3

What is the probability of rolling an even number on a six-sided die?

• 1/6

• 1/4

• 1/2

• 1/3

What is the probability of rolling a number greater than 2 on a six-sided die?

• 3/4

• 1/3

• 1/2

• 2/3

What does theoretical probability depend on?

• None of the above

• Actual outcomes

• Past events

• Predicted outcomes

How is experimental probability calculated?

• Number of desired outcomes over total outcomes

• Number of trials over number of successes

• Number of outcomes over number of events

• Number of successes over number of trials

What distinguishes experimental probability from theoretical probability?

• Theoretical is based on actual outcomes

• Experimental is based on predictions

• Experimental is based on actual outcomes

• Theoretical is always more accurate
