A bag has 3 red marbles, 3 blue, 4 green and 2 yellow. What is the theoreticalprobability of pulling a red marble?Write your answer as a fraction, decimal, and percent.
[tex]\begin{gathered} \text{red}=3 \\ \text{blue =3} \\ \text{green}=4 \\ \text{yellow}=2 \\ \text{Total}=3+3+4+2 \\ \text{Total =12} \\ A=\text{Pulling a red marble} \\ P(A)=\frac{3}{12}=\frac{1}{4} \\ \\ \text{The probability of pulling a red marble is }\frac{1}{4}\text{ or 0.25 or 25\%} \end{gathered}[/tex]
