A standard normal distribution has a mean of zero; half the bell curve is to the left of zero and half to the right.
A standard normal distribution has a standard deviation of 1 and follows the 68-95-99.7 rule; e.g. 99.7% of the probability is between -3 and +3.

The post is on the first quadrant at the coordinates (3, 2).
Step-by-step explanation:
Step 1; First we need to determine which quadrant the point (-3, 2) is on. The coordinate has a negative value of x which denotes it could be located on either the second or third quadrant. The y coordinate has a positive value so out of the second and third quadrant, it is located in the second quadrant.
Step 2; The fence post is reflected over the y-axis which means the coordinate values remain the same but the symbols are in accordance with the first quadrant. In the first quadrant, both x coordinates and the y coordinates are positive. So the co-ordinate for the reflected fence post is (3, 2).
