📐 How It Works

The Prediction Formula

Expected Outcomes = P(event) × Number of Trials

1

Find or write the probability as a fraction, decimal, or percent.
P(heads) = 1/2

2

Identify the number of trials (how many times the event is repeated).
120 coin flips

3

Multiply: P(event) × trials to get the expected count.
1/2 × 120 = 60 heads expected
