1. Items are inspected for flaws by two quality inspectors. If a flaw is present, it will be detected by the first inspector with probability 0.9 and by the second with probability 0.7. Assume the inspectors function independently. a) If an item has a flaw, what is the probability that it will be found by both inspectors?
b) If an item has a flaw, what is the probability that it will be found by at least one of the two inspectors?
c) Assume that the second inspector examines only those that have been passed by the first inspector. If an item has a flaw, what is the probability that the second inspector will find it?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer is

d.
