Probability Review

Maryn rolls a die 6 times and gets a 2 three times. How does the experimental probability of rolling a 2 compare to the theoretical probability?

• Theoretical probability is greater than experimental

• Experimental probability is greater than theoretical

• Theoretical probability is the same as the experimental

• Probability cannot be determined

Joshua flips a coin 100 times. It lands on tails 67 times. How does the theoretical probability compare to the experimental probability?

• Theoretical probability is higher by 17%

• Theoretical probability is higher by 67%

• Experimental probability is higher by 17%

• Experimental probability is higher by 67%

Probability can be expressed as a number between _____

• 0 - 1

• 0 - 10

• 1 - 100

Justin opens a bag of Starbursts, picks a piece, records the color, and returns it. His results were:

6 red

5 yellow

10 pink

4 orange

Which color's experimental probability is closest to its theoretical probability?

• red because the theoretical probability is 25%

• pink because the theoretical probability is 25%

• yellow because the theoretical probability is 20%

• orange because the theoretical probability is 16%

Asa spins the spinner 150 times. Which best represents the results?

• Asa will land on yellow exactly 25 times

• Asa will land on yellow roughly 25 times, but not exactly

• Asa will land on red, green or blue exactly 50 times

• Asa will land on red, green or blue roughly 50 times but not exactly
