The length of time a potential customer visits a website is Exponentially distributed with a mean of
40 seconds.
If the potential customer stays at the website for 60 seconds or more, then the probability
that the customer will place an order is 0.90.
However, if the customer leaves the website within 60 seconds, then the probability they place an order is
only 0.20.
A customer has just placed an order.
What is the probability the customer was at the website for 60 or more seconds?
