Joint Probability Calculator: Determine P(A and B)

Calculate the Joint Probability of A and B Occurring

Enter a value between 0 and 1.
Enter a value between 0 and 1. This is used if events are independent.

Unravel the mystery of simultaneous events! Our Joint Probability Calculator helps you quickly find the likelihood of two or more events occurring together, whether they are independent or dependent. Master joint probability with ease for statistical analysis and decision-making.

Formula:

The joint probability of two events, A and B, is denoted as P(A and B).

  • For Independent Events: P(A and B) = P(A) × P(B)
  • For Dependent Events: P(A and B) = P(A) × P(B|A)
Where:
  • P(A) is the probability of event A occurring.
  • P(B) is the probability of event B occurring.
  • P(B|A) is the conditional probability of event B occurring given that event A has already occurred.
