<h2>Explanation:</h2>
In physics, work is defined force that causes displacement. So this can be expressed by the following equation:
Where:
The force can be found as:
And for the displacement:
The force (weight) is down and the displacement is up, then the work must be negative. So:
Answer:
And using the cdf we got:

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
And 0 for other case. Let X the random variable that represent the random variable of interest and we know that the distribution is given by:
We know the variance on this case given by :
So then the deviation is given by:
And if we solve for we got:
The cumulative distribution function for the exponential distribution is given by:
Solution to the problem
And for this case we want to find this probability:
And using the cdf we got:
