Using the uniform distribution, it is found that there is a 0.9 probability that the tree's angle, from the vertical, will be greater than 4 degrees.
<h3>What is the uniform probability distribution?</h3>
It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value above x is:
In this problem, the bounds are a = 3 and b = 13, hence:
There is a 0.9 probability that the tree's angle, from the vertical, will be greater than 4 degrees.
