Probability of an event is the measure of its chance of occurrence. The event out of the listed events whose probability is 0.2957 is given by : Option C: 
<h3>How to get the z scores?</h3>
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z-score.
If we have

(X is following normal distribution with mean
and standard deviation
)
then it can be converted to standard normal distribution as

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

Also, know that if we look for Z = z in z tables, the p-value we get is

Using the z-table, we get the needed probabilities as:
Case 1:

Case 2:

Case 3:

Case 4:

Thus, the event out of the listed events whose probability is 0.2957 is given by : Option C:
