Independent Probability L2
By Henry Phan
2
Independent Probability
Two events are said to be independent of each other: the probability of one event occurs doesn’t affects the probability of the other event occurring.
Example: you rolled a die and flipped a coin.

Independent Probability
Probability of
Rolling a die: 1/6
Tossing a coin: 1/2
Picking a card: 4/52
