What you will do
Separate a predicted probability from the classical data recorded in finite measurements.
- 01
Prepare a state with a chosen chance of |1⟩.
- 02
Choose one measurement or a larger sample.
- 03
Run fresh preparations and compare sampled frequency with the prediction.
Predict before you measure

Measurement results
What the result shows
One measurement records only 0 or 1. Many fresh preparations reveal a frequency that approaches the underlying probability.
