Math Problem Statement
- An assembly plant receives its voltage regulators from three different suppliera, 60% from supplier B1, 30% from supplier B2, and 10% from supplier B3. Also 95% of the voltage regulators from B1, 80% from B2, and 65% of from B3 perform according to specifications. Let assume A = according to specifications. (5 points) (a) Write down the given values of 60%, 30%, 10%, 95%, 80% and 65% in terms of events A, B1, B2, B3, and operations union, intersection, complement and condition. What is the probability that: (b) any one voltage regulator received by the plant will perform according to specifications? Write down the formula you are using in terms of A and B's. © a particular voltage regulator, which is known to perform according to specifications, came from supplier B3? Write down the formula you are using in terms of A and

P(A) = P(A ∩ B1) + P(A ∩ B2) + P(A ∩ B3)
P(A ∩ Bi) = P(A | Bi) * P(Bi)
P(B3 | A) = P(A ∩ B3) / P(A)
