(b) Items are inspected for flaws by two quality inspectors. If a flaw is present, it will be detected by the first inspector with probability 0.8, and by the second inspector with probability 0.6. Assume the inspectors function independently. (i) . If an item has a flaw, what is the probability that it will be found by both inspectors? (ii). If an item has a flaw, what is the probability that it will be found by at least one of the two inspectors? (iii). Assume that the second inspector examines only those items 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? (iv) If an item has a flaw, what is the probability that first inspector will not find it or the second inspector will not find it?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
