Probability Scale

Relative Frequency
How often something happens divided by all outcomes.

Relative frequency refers to the proportion of times an event occurs and is calculated by dividing the number of times an event occurs by the total number of times an experiment is carried out. So if a coin is tossed 50 times and heads land 30 times, then the relative frequency of a coin toss producing heads is 30/50 or 3/5 or 0.6.

Coin Toss

Task:
1. Predict how many times you will get a head if you toss a coin in the air 20 times. Record your prediction.
2. Toss the coin 20 times and record the results.
3. What can you conclude from your results.
