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 inspector 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?

0.63

0.97

Step-by-step explanation:

Given

Probability to detect the flaw by first inspector is 0.9

Probability to detect the flaw by second inspector is 0.7

(a)Probability that both inspector find the flaw

(b)Probability of finding flaw by at least one inspector is

P=1-Probability of not detecting the flaw by both inspectors

P=1-0.03=0.97

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
