Simple vs Compound Probability

How do you find compound probability?

• multiply the probability of each event that is occurring

• add the probability of each event that is occurring

• divide the probability of each event that is occurring

• Subtract the probability of each event that is occurring

A bag of marbles contains 8 green, 4 blue, 10 red and 2 yellow colored marbles. A marble is drawn randomly, then replaced, and another is drawn.

Find P(red, then yellow)

• 5/138

• 5/288

• 5/144

• 5/12

Based on the chart, what is the experimental probability of pulling a green marble?

• 1/8

• 8/25

• 8/100

• 7/8

Victor picks a card at random. Without putting the first card back, he picks a second card at random.

• dependent

• independent

What is the probability you spin an odd number and not yellow?

• 5/18

• 1/9
