Theoretical and Experimental Probability

Front

What is Theoretical Probability?

Back

Theoretical Probability is the likelihood of an event happening based on all possible outcomes. It is what should happen in an ideal situation.

Front

What is Experimental Probability?

Back

Experimental Probability is the likelihood of an event happening based on actual experiments or trials. It is what does happen in practice.

Front

How do you calculate Theoretical Probability?

Back

Theoretical Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

If a spinner has 4 equal sections numbered 1 to 4, what is the theoretical probability of landing on a 3?

Back

1/4

A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles. What is the theoretical probability of pulling a blue marble?

Back

2/10 or 1/5

Front

What is the formula for calculating Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials).

Front

If a spinner has 8 equal sections and 2 are yellow, what is the theoretical probability of landing on yellow?

Back

2/8 or 1/4

Front

In a bag with 4 red, 3 blue, and 5 green marbles, what is the theoretical probability of pulling a red marble?

Back

4/12 or 1/3

Front

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.

Front

What does it mean if an event has a probability of 1?

Back

It means the event is certain to occur.
