Answer:
the answer is 6
Step-by-step explanation:
you take the absolute value for both of them which is 2 and 8 but you keep the negative still so it would be -2+8 which is 6
Number of returns = 47
Number of returns that contain errors = 5
Number of returns that does not contain error = 47 - 5 = 42
P(selecting none that contains error in the unreplaced selection) = 42/47 x 41/46 x 40/45 = 68880 / 97290 = 0.708
option C is the correct answer.
