2x - 3y = -2  ⇒ 4x - 6y = -4
4x +  y = 24 ⇒  <u>4x + y = 24</u>
                              <u>-7y</u> = <u>-28</u>
                               -7      -7
                                 y = 4
                     2x - 3(4) = -2
                       2x - 12 = -2
                       <u>     +12  +12</u>
                              <u>2x</u> = <u>12</u>
                               2      2
                               x = 6
                         (x, y) = (6, 4)

: A personal computer manufacturer buys 36% of its chips from Japan and the rest from the United St...
meriva

Answer: 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

P(D)=P(D|J)\times P(J)+P(D|U)\times P(U)\\\\\Rightarrow\ P(D)=0.017\times0.36+0.012\times0.64=0.0138

Thus , the probability that chip is defective = 0.0138

Then , the probability that a chip is defect-free=1-0.0138=0.9862
