What is experimental probability?

Back

Experimental probability is calculated based on the results of an experiment or trial.

Front

What is theoretical probability?

Back

Theoretical probability is calculated based on the possible outcomes in a perfect scenario.

Front

How do you calculate the probability of an event?

Back

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

What is the probability of rolling a 1 on a fair six-sided die?

Back

P(1) = 1/6.

Front

If you roll a die 5 times and get 1, 3, 3, 4, 4, what is the experimental probability of rolling a 1?

Back

P(1) = 1/5.

What is the probability of spinning an even number on a spinner with numbers 1 to 6?

Back

P(even) = 3/6 = 1/2 = 50%.

Front

What is P(not A)?

Back

P(not A) = 1 - P(A).
