How can I use matlab to solve this probability problem ?

Create the mathematical model of the following problem and compute the desired result using exhaustive search in matlab; There are 100 people who want to connect to a system through k channels. The probability that a person wants to connect to the system is 0.8. A channel can only be used by one person at a time. A connection failure occurs if a person wants to connect to the system but all the channels are occupied by other users. What is the minimal k if the probability for connection failure is less than 1%?

Where is MATLAB? It's just your homework or something

The question is to be solved on MATLAB. It's written in the first line of the statement.
