Afirm buys components from two suppliers: 60 percent from supplier a and the rest from supplier b. it so happens that 9 percent of the components from supplier a are defective and 15 percent of the components from supplier b are defective. (a) what is the probability that the next component the firm buys is defective? (b) what is the probability that the component that the firm buys is from supplier b if we know that it is defective?

Step-by-step explanation:

Given that a firm buys  components from two suppliers:

A : 60%  Defective 9%

B:40%  Defective 15%

a) the probability that the next component the firm buys is defective

=prob purchased from A and defective + prob purchased from B and defective

=

b)  the probability that the component that the firm buys is from supplier B if we know that it is defective

=Prob from B and defective/Prob defective

=

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
