The probability of all independent events occurring refers to the likelihood that multiple independent events will all happen simultaneously. For independent events, the probability of their intersection is simply the product of their individual probabilities.
The calculator uses the multiplication rule for independent events:
Where:
Explanation: This formula only applies when events A, B, and C are independent, meaning the occurrence of one event does not affect the probability of the others.
Details: Calculating the probability of multiple independent events occurring is fundamental in statistics, risk assessment, decision-making, and various scientific fields. It helps in understanding the likelihood of complex scenarios.
Tips: Enter probabilities for events A, B, and C as values between 0 and 1. All probabilities must be valid (0 ≤ probability ≤ 1). The calculator will compute the probability that all three events occur.
Q1: What does it mean for events to be independent?
A: Events are independent if the occurrence of one event does not affect the probability of the other events occurring.
Q2: Can this formula be used for dependent events?
A: No, for dependent events, you would need to use conditional probabilities: P(A∩B∩C) = P(A) × P(B|A) × P(C|A∩B).
Q3: What if I have more than three events?
A: The same principle applies - multiply all individual probabilities: P(A∩B∩C∩D...) = P(A) × P(B) × P(C) × P(D) × ...
Q4: What is the range of possible results?
A: The result will always be between 0 and 1, where 0 means impossible and 1 means certain.
Q5: How do I convert percentages to probabilities?
A: Divide the percentage by 100. For example, 25% becomes 0.25 as a probability.
