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.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
