Step-by-step explanation:
Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
The answer is D because when you insert it into a calculator it gives you D. Yet, if you do it manually you still get the same number .
27.12 - 4.8 = 22.32
Multiply by one 22.32= 22.32
2x2= 4
22.32 - 4 = 18.32
