Using the table below showing the number of students who are taking a statistics course in the traditional
face-to-face mode versus online by gender. Assume one person is chosen at random from the 220.
What is the probability that person is an online student who is also male. 
            online  tradition   total
men          30      60           90
female       40      90           130

total        70      150          220


Solution 

    P = 30%2F220,


which you can simplify to


    P = 3%2F22.


The formula is self-explanatory.
