one box contains 5 products from machine A and 3 products from machine B. it is known form past experience that 1% and 2% of the products made by each machine, respectively, are defective. suppose that two products are randomly selected from the box. (a) What is the probability that one of them is defective? (b) If two products were chosen randomly and found to be defective, what is the probability that they were made by machine B?

what am i trying to find out. you didn't put up the whole question.

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
