21 22 23 24 25 TIME REMAINING 01:40:27 A hat contains slips of paper with the names of the 26 other students in Eduardo’s class
Pani-rosa [81]

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 _{16}C_2.)


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 \frac{120}{325} = \frac{24}{65}


Example: how to compute C(16,2):


C(n, r) = \frac{n!}{r!(n-r)!} \\ C(16, 2) = \frac{16!}{2!(16-2)!} \\ =\frac{16!}{2! \times 14!} \\ =\frac{16\times 15}{2\times 1} \\ =120

A chef had 7 potatoes. How many could he make if each bowl using one-seventh of a potato?
seraphim [82]
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.
