:a personal computer manufacturer buys 36% of its chips from japan and the rest from the united
a personal computer manufacturer buys 36% of its chips from japan and the rest from the united states. of the japanese chips, 1.7% are defective, and 1.2% of the american chips are defective.
find the probability that a chip is defect-free. (round your answer to four decimal

0.9862

Step-by-step explanation:

Given : The probability that the chips belongs to Japan: P(J)= 0.36

The probability that the chips belongs to United States : P(U)= 1-0.36=0.64

The proportion of Japanese chips are defective : P(D|J)=0.017

The proportion of American chips are defective : P(D|U)=0.012

Using law of total probability , we have

Thus , the probability that chip is defective = 0.0138

Then , the probability that a chip is defect-free=

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
