Jackson is playing a game of chance where he must randomly draw a marble out of a jar. He calculates the probability of drawing
Sindrei [870]

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}.

What value of R makes r/ -11 = (-3) true
marissa [1.9K]

Answer:

The value of r=33 which makes the equation true.

Step-by-step explanation:

Given the equation

\frac{r}{-11}=-3

We have to find the value of r for which the equation must be true.

solving the equation

\frac{r}{-11}=-3

Multiply both sides by -11

\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)

r=33

Therefore, the value of r=33 which makes the equation true.

<u>VERIFICATION:</u>

Putting r=33 in the equation

\frac{r}{-11}=-3

\frac{33}{-11}=-3

-3=-3              ∵ \frac{33}{-11}=-3

L.H.S = R.H.S

Therefore, the value of r=33 which makes the equation true.
