Question

a bag contains 8 red marbles 5 blue marbles 8 yellow marbles what is the probability of choosing a red marble if a single choice is made from the bag

Answer 1

`(8)/(21)`

8 + 8 + 5 = 21

`(8)/(21)` = probability of getting a red marble

`(8)/(21)` = probability of getting a yellow marble

`(5)/(21)` = probability of getting a blue marble
