A) $0.4878$
B) $0.5122$
C) $0.6831$
D) $0.0122$

The area under the standard normal curve between $z = -2.25$ and $z = 0$ represents the probability of a z-score falling within that range. This area can be found using a standard normal distribution table or calculator, which gives the probability as $0.4878$. This means there is a 48.78% chance that a z-score will fall between -2.25 and 0 in a standard normal distribution.
