: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=

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
