Experimental and Theoretical Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated using the formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

How can probability be expressed?

Back

Probability can be expressed as a fraction, a decimal, or a percent.

Front

What is the formula for calculating the probability of an event not occurring?

Back

P(Not A) = 1 - P(A), where P(A) is the probability of the event occurring.

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on actual experiments or trials, calculated as: P(Event) = Number of times the event occurs / Total number of trials.

If a spinner has 8 equal sections and 1 is yellow, what is the theoretical probability of landing on yellow?

Back

Front

If a spinner has 8 equal sections and 7 are not yellow, what is the theoretical probability of NOT landing on yellow?

Front

What does a probability of 0 mean?

Back

A probability of 0 means that the event cannot occur.

Front

What does a probability of 1 mean?

Back

A probability of 1 means that the event is certain to occur.

Front

What is a likely chance event closer to?

Back

A likely chance event is closer to the number 1.

Front

What is the range of probability values?

Back

Probability values range from 0 to 1, where 0 indicates impossibility and 1 indicates certainty.
