a) Fact: the region under the standard normal curve that lies to the left of $-1.43$ has area $0.076358$.

Without consulting a table or a calculator giving areas under the standard normal curve, determine the area under the standard normal curve that lies to the right of 1.43.
answer:

b) Which property of the standard normal curve allowed you to answer part a)?
A. Almost all the area under the standard normal curve lies between $-3$ and $3$
B. The standard normal curve extends indefinitely in both directions
C. The total area under the curve is 1
D. The standard normal curve is symmetric about 0
E. None of the above
