Question

HELP PLZZZZ 30 POINTS IF RIGHT A bag contains 5 red marbles, 3 green marbles and 2 blue marbles. What is the probability of randomly selecting a blue marble out of the bag?

Answer 1

`(1)/(5)` or 20%

Explanation:

Probability is expressed as a fraction where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since there are 10 total marbles and 2 of them are blue, the probability of randomly selecting a blue marble is:

`(blue)/(marbles)=(2)/(10)=(1)/(5)`

or 20%
