Answer:
The probability is 0.0015
Step-by-step explanation:
We know that the mean
is:

The standard deviation
is:

The Z-score is:

We seek to find

The Z-score is:




The score of Z = 3 means that 7:15 p.m. is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%
So

X=12 because I said so and I’m smart
