Question

Find the probability of the event if a single choice is made from a bag.A bag contains 3 red marbles, 6 blue marbles, 2 yellow marbles, and 8 green marbles. What is the probability of choosing a red marble when one marble is drawn?

Answer 1

To answer this question, we will use the following expression to find the probability:

`\frac{\text{favorable outcomes}}{total\text{ outcomes}}.`

Since there are 3 red marbles, the number of favorable cases is 3. The total number of marbles is

`3+6+2+8=19,`

therefore, the total number of outcomes is 19.

Substituting the above values in the expression, we get:

`(3)/(19)\text{.}`

Answer:

`(3)/(19)\text{.}`
