Let X the random variable that represent the number of new visitors to a website in one hour. We know that
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
Solution to the problem
On this case we are interested on the probability of having no visitors to the website:.
Using the pmf we can find this probability like this:
Answer:
At 8 hours, option 2 would first have a higher pay
When it is said that a variable is inversely proportional to another, it is best to write out an equation to represent it.
This means;
y=k/x (where k is a constant number like 1 or 2, etc)
If you double x, the value of y is halved. I have attached a graph that shows this.
Hope I helped :)
