Find the probability that two events both occur.

P(A and B) 0.15

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

Step-by-step with your numbers:
1. Values used:
2. P(A) = 0.5
3. P(B) = 0.3
4.
5. P(A and B) = P(A) x P(B) = 0.5 x 0.3 = 0.15
Did we solve your problem today?

For independent events, the chance both happen is the product of their probabilities.

The math behind it

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

Worked example

0.5 and 0.3 → 0.15.

FAQ

What if they're dependent?

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