Two components from batch are randomly selected and tested. what are the probabilit es essociated with 0 1 and 2 defective components being in the batch under each of the following conditions? Round your answers to four deci al places. (a) Neither tested component is defective. no defective components one defective component two defective components (b) One of the two tested components is defective. [Hint: Draw a tree diagrem with three first-generation brenches for the three different types of batches.] no defective components one defective component two defective componentsExplanation / Answer
P(D) = 0.71
P(D|L) = 0.65
P(D'|L') = 0.86
a)
P(D'|L) = 1 - P(D|L)
= 1 - 0.65 = 0.35
b)
P(D|L') = 1- P(D'|L')
= 1 - 0.86
= 0.14
