A bag contains 1 blue, 2 green, 3 yellow, and 3 red marbles, as shown.

What is the probability of drawing a red marble out of the bag without looking?

|\Omega|=1+2+3+3=9\\|A|=3\\\\P(A)=(3)/(9)=(1)/(3)\approx33,3\%

first we add up the number of marbles which would be 1+2+3+3=9 then we do 3/9 and get .33333333 and we would then turn it into a percent 33.33%
