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

<h2 />

$\frac{6}{18}$ (B.)

<h2 />

6 + 5 + 4 + 3 = 18

$\frac{6}{18}$ = probability of getting a green marble

$\frac{5}{18}$ = probability of getting a yellow marble

$\frac{4}{18}$ = probability of getting a red marble

$\frac{3}{18}$ = probability of getting a purple marble
