Question

A bag held 3 red marbles, 1 blue marble, and 4 yellow marbles. Lee drew a red marble

and did not replace it. What is the probability of drawing a yellow marble next?
A. 1/4
B. 1/3
C. 1/2
D. 4/7

Answer 1

Explanation:

3 red marbles

1 blue marble

4 yellow marbles

8 marbles in all

Lee draws a red marble that was not replaced so basically you will have 7 marbles. So the answer would be 4/7

Answer 2

Explanation:

3 red, 1 blue, and 4 yellow...thats a total of 8 marbles

so a red was drawn and not replaced....means we now have 7 marbles.

P(yellow) : since we still have 4 yellow and there are a total of 7 marbles, the probability of drawing a yellow is : 4/7 <==
