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.

What is a compound event in probability?

Back

A compound event is when two or more independent events occur together.

If a bag contains 12 shapes (3 circles, 4 squares, 5 triangles), what is the probability of pulling out a circle?

Back

The probability of pulling out a circle is 3/12 or 1/4.

Front

How do you calculate the probability of an event?

Back

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

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.
