Question

Look at the graph and the uniform Destiny function for a friend who is X minutes late find the probability that the friend is at least 19 minutes late

Answer 1

If the friend is at least 19 minutes late, we have all x-values from 0 to 19 included for the solution.

The probability of each value is 1/30, so the probability from all values until 19 is:

$19\cdot\frac{1}{30}=\frac{19}{30}$
