AND Probability Calculator

Find the probability that two events both occur.

Calculated Output

P(A and B) 0.15

Formula: P(A and B) = P(A) × P(B) (independent)

Step-by-Step Breakdown

1. Values used:

2. P(A) = 0.5

3. P(B) = 0.3

5. P(A and B) = P(A) x P(B) = 0.5 x 0.3 = 0.15

Did this calculator solve your problem today?

The math behind it

P(A and B) = P(A) × P(B) when the events are independent.

0.5 and 0.3 → 0.15.

What if they're dependent?

Use P(A) × P(B|A) with the conditional probability.
