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

Probability of drawing a white marble out of bag =
`(1)/(10)`

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=(n(S))/(n(E))=(3)/(30)=(1)/(10)`

So the answer is probability =
`(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%.
