A bag contains 3 blue marbles, and 4 orange marbles. If 2 marbles are selected, what is the probability of picking 2 orange marbles?
There are \(\displaystyle C(7,2)=21\) to select 2 marbles. There are \(\displaystyle 6\) ways to select 2 orange from 4 orange. This gives the probability \(\displaystyle \frac{2}{7}\)
