The problem asks for the probability that a $$ z $$-score is less than $$ 1.44 $$. In other words, we need to find
$$
P(Z < 1.44),
$$
where $$ Z $$ follows a standard normal distribution.

To solve this:

1. We refer to the standard normal distribution table (or use a calculator). The table gives the cumulative probability from the left up to a given $$ z $$-score.
2. Looking up $$ z = 1.44 $$ in the table, we obtain approximately
   $$
   P(Z < 1.44) \approx 0.9251.
   $$

Thus, the probability that a $$ z $$-score is less than 1.44 is $$ 0.9251 $$.

The correct answer is:
- $$ 0.9251 $$
The probability that a z-score is less than 1.44 is 0.9251.
