a personal computer manufacturer buys 36% of its chips from japan and the rest from the united states. of the japanese chips, 1.9% are defective, and 1.2% of the american chips are defective.
find the probability that a chip is defective. (round your answer to four decimal

The probability is 0.0145.

Step-by-step explanation:

We first calculate two probabilities:

And then we sum them up.

Given that the probability of finding a defective chip is conditioned by the probabilities of the chips come from, we deduce that we'll have to use the formulae for extraction without replacement:

P(D∪J) = P(J)*P(D/J)

P(D∪A) = P(A)*P(D/A)

We know that

So we can simply calculate

P(D∪J)+P(D∪A) =

P(D∪J)+P(D∪A) =

Therefore the rounded answer to 4 decimals would be 0.0145.

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
