iM2 #61 Theoretical vs Experimental Probability2

The table to the right shows the results of a spinner experiment. If the spinner is spun 12 times, what is the theoretical probability of landing on a KMS color?

• 2/5

• 2/12 = 1/6

• 6/12 = 1/2

• 4/12 = 1/3

The table to the right shows the results of a spinner experiment. If the spinner is spun 12 times, what is the experimental probability of landing on a KMS color?

• 2/5

• 2/12 = 1/6

• 6/12 = 1/2

• 4/12 = 1/3

How do the results compare (the theoretical compared to the experimental)?

• the theoretical probability is equal to the experimental probability

• the theoretical probability is less than the experimental probability

• the theoretical probability is greater than the experimental probability

What is the theoretical probability of the spinner landing on a multiple of 3? (percent)

• 3/8 = 37.5%

• 2/8 = 25%

• 1/8 = 12.5%

• 1/2 = 50%

What is the theoretical probability of landing on a 7? (decimal)

• 3/8 = 37.5%

• 2/8 = 25%

• 1/8 = 12.5%

• 7/8 = 87.5%

Complimentary probability means ONE WHOLE. The probability of rolling a 5 or 6 on one di and the probability of rolling a 1,2,3 or 4 on another di. (circle one)

• complementary

• not complementary

A spinner has purple, green, orange, blue and red sections. The probability of spinning orange or red and then the probability of spinning green or blue. (circle one)

• complementary

• not complementary

The spinner was spun 200 times. The results are on the bar graph below.

What is the theoretical probability of spinning and landing on a 4?

• 40/200 = 1/5

• 37/200

• 4/200 = 1/50

• 4/5

What is the experimental probability of landing on a 4?

• 40/200 = 1/5

• 37/200

• 4/200 = 1/50

• 4/5

How do the results compare (the theoretical compared to the experimental)?

• the theoretical probability is equal to the experimental probability
