Question

A bag contains 8 green marbles, 16 red marbles, 3 white marbles, and 3 black marbles. What is the probability of drawing a white marble out of the bag?

Answer 1

Answer:

Probability of drawing a white marble out of bag = $\frac{1}{10}$

Step-by-step explanation:

A bag contains 8 green marbles, 16 red marbles, 3 white marbles, and 3 black marbles.

So total number of marbles = 8 + 16 + 3 + 3 = 30

So the set of total events n(E) = 30

Now we have to tell the probability of drawing a white marble out of the bag.

From the given data number of white marbles or set of preferred events n(S) =  3

Now probability to draw a white marble $P=\frac{n(S)}{n(E)}=\frac{3}{30}=\frac{1}{10}$

So the answer is probability = $\frac{1}{10}$

Answer 2

There is a 10% (1/10) chance of drawing a white marble out of the bag.

Altogether, there are 30 marbles in the bag (8 + 16 + 3 + 3 = 30)

3 of the marbles are white. That makes the probability of drawing a white marble 3 out of 30, or 1/10 or 10%.
