# Math Help - Quick little probability question

1. ## Quick little probability question

2 students are randomly picked one after the other in a class of 30.
What is the probability that you get picked and your friend does not get picked?
Thanks

Because the question is so poorly put we must make some assumptions.
Say that you have a special friend J.
There are 28 ways for you to be selected but not J.
There ${{30}\choose {2}}$ ways to make all of the selections.
