Question: For a normal distribution, use the given z-scores to find the requested probability:
Probability is greater than or equal to a z score of 2.
I drew a distribute (picture this: the mean of 0 set at the middle and a line drawn at 2 shaded to the right).
But how do I go about finding the area of the shaded region?

The table reads "less than" so you do 1 - (the z-score table value corresponding to 2)
use the z-score table to find the portion of the population below 2
the number should be something like .9772
the probability of a z-score above this is ... 1 - .9772
