Using complementary events, considering a 
probability of drawing a red marble, the probability of not drawing a red marble is of 
.
<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 probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:
The probability of not drawing a red marble is of .
