To answer this question, we will use the following expression to find the probability:


\frac{\text{favorable outcomes}}{total\text{ outcomes}}.

Since there are 3 red marbles, the number of favorable cases is 3. The total number of marbles is


3+6+2+8=19,

therefore, the total number of outcomes is 19.

Substituting the above values in the expression, we get:


(3)/(19)\text{.}

Answer:


(3)/(19)\text{.}
