Experimental and Theoretical Probability

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted.

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate the probability of an event?

Back

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

Front

If a spinner has 4 equal sections, what is the probability of landing on any one section?

Back

1/4 or 25%.

Front

What is the theoretical probability of NOT landing on a specific color if the spinner has 8 equal sections and 1 section is that color?

Back

7/8.

Front

If a spinner has 3 sections colored red, 2 sections colored blue, and 1 section colored yellow, what is the theoretical probability of landing on blue?

Back

2/6 or 1/3.

Front

What is the formula for calculating the probability of multiple independent events occurring?

Back

P(A and B) = P(A) * P(B).

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and results, while theoretical probability is based on expected outcomes.

Front

If a spinner is spun 200 times and lands on a number 50 times, what is the experimental probability of landing on that number?

Back

50/200 or 1/4.

Front

What is the theoretical probability of landing on a number greater than 2 if a spinner has numbers 1 to 4?

Back

2/4 or 1/2.
