From a group of 7 people, you randomly select 2 of them. what is the probability that they are the 2 of the oldest people in the group? give your answer as a fraction.

i just took the test, the correct answer is .. 31.5 in.

-2 is the right

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
