Predict counts from probabilityProbability as a fraction
Predict how many times each event happens.
P(heads) = 45. In 200 flips, how many are heads?
P(heads) = 12. In 300 flips, how many are heads?
P(blue) = 910. In 20 draws, how many are blue?
P(blue) = 14. In 100 draws, how many are blue?
P(red) = 45. In 80 spins, how many land on red?
P(heads) = 34. In 100 flips, how many are heads?
P(red) = 14. In 60 spins, how many land on red?
P(heads) = 110. In 60 flips, how many are heads?
P(heads) = 25. In 80 flips, how many are heads?
P(a win) = 2325. In 300 games, how many are wins?
The counting principleTwo stages
