Calculate the probability of single events, multiple independent events occurring together, and conditional probability. Results in fraction, decimal, and percentage.
A number between 0 and 1 representing likelihood of an event. 0 = impossible, 1 = certain. Fair coin flip = 0.5.
P(B|A) is the probability of B given A has occurred.
For independent events: P(A and B) = P(A) × P(B). Rolling 6 twice: 1/6 × 1/6 = 1/36.
P(not A) = 1 - P(A). If rain probability is 30%, no rain probability is 70%.
Theoretical is calculated mathematically. Experimental is observed over many trials. They converge as trials increase.
