Key concepts

3 concepts

  1. 1

    Experimental probability is found by calculating the relative frequency of an event based on actual experimental outcomes.

  2. 2

    To find the experimental probability, divide the number of times an outcome occurs by the total number of trials.

  3. 3

    The expected frequency can be predicted by multiplying the experimental probability by a new number of trials.

Practice

9 questions

1

What is the range of values that probabilities can have?

2

Explain the difference between experimental probability and theoretical probability (which is not covered in the video). Which type of probability is discussed in the video?

Quick comprehension check

A spinner has 5 equally sized sections numbered 1 to 5. You spin the spinner 30 times and record the number it lands on each time. The results are: 1 (8 times), 2 (5 times), 3 (6 times), 4 (7 times), 5 (4 times). What is the experimental probability of spinning a 4?
