Question

An experiment consists of randomly drawing a cube from a bag containing three red and

two blue cubes.
1. What is the sample space of this experiment?
2. List the probability of each outcome in the sample space.
3. Is the probability of selecting a red cube equal to the probability of selecting a blue
cube? Explain
4. What color cube would you need to add to the bag to make the outcomes equally
likely?

Answer 1

1. Sample space: red or blue

2. Red: 3/5, Blue 2/5

3. 60% probability of selecting a red, 40 percent probability

4. 1 more blue

Explanation:

3. 3/5 x 2 = 6/10 --> 60%

4. 5 total, 3 red, 2 blue (+ 1 blue) = 6 total, 3 red, 3 blue
