In probability theory, the multiplication rule states that:
There is a 0.01 (1%) probability that a seal will fail if the joint is not coated with a sealing compound before assembly. The proportion of joints that are not coated is 0.05 (5%).
What is the probability that a seal will fail.
| P(A|B) |
Probability that the seal will fail if not coated |
0.01 |
| P(B) |
Probability the seal will not be coated |
0.05 |
 |
0.01 x 0.05 |
=0.0005 |
