Question

A bag has 11 red marbles and 4 yellow marbles. Half of the yellow marbles are made of plastic. A marble is selected at random from the bag. What is the probability that it is a yellow, plastic marble? Write your answer as a fraction in simplest form.

Answer 1

Explanation:

total marbles=11+4=15

plastic yellow marbles=4/2=2

P=(plastic marbles)/(total marbles)=2/15

Answer 2

2/15

Explanation:

11+4 = 15 marbles

Half of the yellow marbles are made of plastic = 2 plastic yellow marbles

P(yellow plastic marbles) = number of yellow plastic marbles / total

=2/15
