The value of the probability P(A and B) is 0.12
<h3>How to determine the probability?</h3>
The given parameters are
P(A) = 0.40
P(B) = 0.30
Given that the events are independent events;, we have:
P(A and B) = P(A) * P(B)
So, we have:
P(A and B) = 0.40 * 0.30
Evaluate
P(A and B) = 0.12
Hence, the value of the probability P(A and B) is 0.12

- - Solve:
To find the volume of a sphere:

3.14≈π
Now since its telling us to use π, then we do our formula by multiplying by π.
π=3.14 (Approximate amount)
So:

So you are correct.
When Radius=9, you plug in for R. :)
