Answer:

[tex]\displaystyle \frac{5}{20}[/tex]

Step-by-step explanation:

    We will put the number of wanted outcomes over the number of possible outcomes.

[tex]\displaystyle \frac{\text{wanted outcomes}}{\text{possibly outcomes}} =\frac{\text{red marbles}}{\text{number of all marbles in the bowl}}=\frac{5}{5+7+8} =\frac{5}{20}[/tex]
