Ok, so I know that the

probability of seniors who prefer pepperoni is 17:31

probability of seniors who prefer supreme is 12:31

probability of seniors who prefer cheese is 2:31

Is the answer simply 17:31 or what do I need to do to figure this out?

This part is the original question:

Of 31 college seniors at Southern Swampland University, 17 preferred pepperoni, 12 preferred supreme, and 2 preferred cheese. If we picked a college senior at Southern Swampland University at random, what is the probability that he or she would prefer pepporoni?

I was just showing what I started, but then got really confused.

After that, it;s just arithmetic. Write 17:31 however you have to write it so that it answer the question. 17/31? 0.548? 54.8%? Really, whatever it takes.
