Understanding Experimental Probability and Expectation

Key concepts

What you'll likely be quizzed about

Experimental probability measures the likelihood of an event based on the outcomes of experiments.
It is calculated by dividing the number of successful trials by the total number of trials conducted.
For instance, if a coin is flipped 100 times and lands on heads 60 times, the experimental probability of getting heads is 60 out of 100, or 0.6.

What is a simple example of experimental probability?

Click to reveal answer

Flipping a coin 10 times to record the number of heads shows experimental probability.

Key notes

Important points to keep in mind

Experimental probability comes from trials; expectation from outcomes.

Expectation can guide decisions with predictions.

More trials typically yield more reliable experimental probabilities.
