A spinner has 5 sections of equal size labeled P, Q, R, and T.
The arrow of this spinner was spun 15 times and landed 4 times on the section labeled Q.

• The experimental probability is ¹/₅, and the theoretical probability is ¹/₅.
• The experimental probability is ¹/₅, and the theoretical probability is ⁴/₁₅.
• The experimental probability is 4/₁₅, and the theoretical probability is ¹/₅.
• The experimental probability is 4/₁₅, and the theoretical probability is ⁴/₁₅.

The spinner has 6 sections of equal size.
The arrow of the spinner was spun 60 times. On 45 out of 60 times, the arrow landed on a section labeled with a multiple of 4. What was the experimental probability of the arrow landing on a section labeled with a multiple of 4?

• ¹/₃
• 1/₂
• ²/₃
• ³/₄

Tia generated a list of random numbers to simulate an experiment based on the waiting times at a supermarket checkout line.  The number 1 represents waiting in line less than 5 minutes and the number 2 represents waiting in line 5 minutes or more:
1, 1, 1, 1, 2, 1, 1, 1, 2, 1, 2, 2, 1, 2, 2, 1, 1, 2, 2, 1, 1, 2, 2, 2, 1
Which conclusion can Tia most reasonably draw from the simulation?

• A person is likely to wait in line less than 5 minutes 14% of the time
• A person is likely to wait in line 5 minutes of more 11% of the time
• A person is likely to wait in line less than 5 minutes more than 50% of the time
• A person is likely to wait in line 5 minutes or more 50% of the time

as the number of trials in an experiment increases, the experimental probability of an event approaches the theoretical probability of the same event, meaning the difference between the experimental and theoretical probability will be closer to zero 

• fundamental counting principal 
• independent event
• inference
• law of large numbers
