Good point, but it really didn't need all that computing power:
Let x be the standardized value, n be a given value, m be the mean, and s be the standard deviation.
x = (n - m) / s
x = (5 - 13.5) / 6.2 = approximately -1.4
P(t < 5) = P(x <1> 1.4) = 0.5000 - 0.4192 = 0.0808 = 8.08%
Hence, the probability is 0.0808 or 8.08%. Well close enough!

Thank goodness for that; I hate basement apartments!
There is a single 21-foot vertical pine tree growing in the middle of Marks large flat yard. On a certain day, the sun will rise at 6:00 am and set at 6:00 pm.
At noon on that day the sun will be directly overhead and the trunk of the pine tree will cast no shadow. A traveler lay down the night before this special day, and was awakened in the morning when the sun's rays reached his eyes, which were 13 feet due west from the tree.
To the nearest minute at what time did he awake
