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.
||Probability that the seal will fail
if not coated
||Probability the seal will not be coated
||0.01 x 0.05
