Question

Jackson is playing a game of chance where he must randomly draw a marble out of a jar. He calculates the probability of drawing a red marble to be . What is the probability of not drawing a red marble?

Answer 1

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

What are complementary events?

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 $\frac{3}{4}$.
