Full solution stays hidden until you ask for it.
1. Identify the condition event probability P(B).
2. Identify the conditional probability P(A|B).
3. Multiply to get the joint probability.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using P(A) when the given conditional is P(A|B) and P(B) is provided.
