Answer:
0.685 = 68.5% probability that X is less than 30 minutes
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

If X has an average value of 26 minutes
This means that 
What is the probability that X is less than 30 minutes?

0.685 = 68.5% probability that X is less than 30 minutes
