Question

Here are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

What is the theoretical probability of randomly drawing a red marble?

Answer 1

5/25

Explanation:

first you count how many there are which is 25 and than you 5 red marbles so it would be 5/25

Answer 2

Probability of randomly drawing a red marble is
`[(1)/(5)`

Explanation:

Given 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. we have to find the 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

As Probability of an event is the chances of an event to occur. It is defined as the favourable outcomes by total number of outcomes.

As no. of red marbles are 5 and

Total number of marbles are 5+8+12=25 marbles.

Hence, probability of randomly drawing a red marble is

`\frac{\text{Favourable outcomes}}{\text{Total number of outcomes}}=(5)/(25)=(1)/(5)`
