Question

A bag has 6 green marbles, 4 red marbles, 5 yellow marbles, and 3 purple marbles. What is the probability of choosing a purple marble?

A.1/6
B.6/18
C.3/20
D.1/9

Answer 1

`(6)/(18)` (B.)

6 + 5 + 4 + 3 = 18

`(6)/(18)` = probability of getting a green marble

`(5)/(18)` = probability of getting a yellow marble

`(4)/(18)` = probability of getting a red marble

`(3)/(18)` = probability of getting a purple marble
