Using complementary events, considering a $\frac{1}{4}$ probability of drawing a red marble, the probability of not drawing a red marble is of $\frac{3}{4}$ .

<h3>What are complementary events?</h3>

They are mutually exclusive events which have the sum of their probabilities as 1.

In this problem, we consider that there is a $\frac{1}{4}$ probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:

$\frac{1}{4} + p = 1$

$p = \frac{3}{4}$

The probability of not drawing a red marble is of $\frac{3}{4}$ .
