Question

There are 6 red marbles and 10 white marbles in a bag. What is probability of randomlychoosing a white marble from the bag?

Answer 1

Given that;

There are 6 red marbles and 10 white marbles

Total marbles is

`6+10=16\text{ marbles}`

To find the probability of randomly choosing a marble, the formula is

`Probability=\frac{Required\text{ outcome}}{Total\text{ possible outcome}}`

Let the probability of randomly choosing a white marble be represented by P(W)

Where the

`\begin{gathered} Required\text{ outcome}=10 \\ Total\text{ possible outcome}=16 \end{gathered}`

The probability of randomly choosing a white marble, P(W) is

`\begin{gathered} P(W)=(10)/(16)=(5)/(8) \\ P(W)=(5)/(8) \end{gathered}`

Hence, the probability of randomly choosing a white marble, P(W) is 5/8
