Question

A marble is drawn at random from the bag. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.

What is the probability that the marble drawn is a green or blue

Answer 1

Total marbles = 20.

Green Marbles = 3

Blue Marbles = 5

3 / 20 = 0.15 = 15%

So there is a 15% chance that you will draw a green marble.

5 / 20 = 0.25 = 25%

So there is a 25% chance that you will draw a blue marble.

Answer 3

P(green or blue)
Green = 3
Blue = 5
Yellow = 4
Pink = 8
Altogether they equal 20
Now add the Green and Blue together
8/20
now simplify
2/5 or 20%
