_____
Above, we have used ⇔ to mean "corresponds to."
There are 26 - 10 = 16 girls. The number of ways to choose 2 girls from a set of 16 is C(16, 2) = 120. (Your class might be using a different notation for combinations, like
.)
The number of ways to choose 2 people (boys or girls) from a set of 26 is C(26, 2) = 325.
The probability of choosing 2 girls is 
Example: how to compute C(16,2):

If each bowl uses one-seventh of a potato, that means the chef can make 7 bowls using one potato. Since there are 7 potatoes, we would multiply 7x7 to get 49 bowls.
49 is your answer.
