multiply probabilities.
Hidden until you reveal it.
Only multiply directly because independence is given.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use independence formula P(A and B)=P(A)P(B).
2. Substitute the two probabilities.
3. Multiply and simplify.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
