Answer

$\frac{1}{4}$

Work Step by Step

To find the probability, first add up all the marbles in the box. $1$ $+$ $1$ $+$ $2$ = $4$ Then see how many red marbles are in the box: $1$. So the probability would be the number of red marbles in the box over the number of total marbles in the box: $\frac{1}{4}$
