Discrete Probability

[dense burrow]

In an urn are 5 blue, 3 red, and 2 yellow marbles. If you draw 2 marbles one at a
time, what is the probability to get at least one red? If you do not put marbles back. We do not distinguish marbles of the same color.
*** i am thinking i would do 1-(7/10*6/9)
is that the correct approach ?
