Probability Types

Classify the following statement as an example of classical, empirical, or subjective probability. After grading the first chapter test the teacher stated that if grades did not get better about 1 out of every 4 students would not pass the class.

• Classical

• Empirical

• Subjective

What describes classical probability?

• Probability that can be calculated using theory, like flipping a coin, drawing a card, or rolling a die.

• Probability that can be calculated once an experiment has been done that has provided resulting data.

• Probability that can be calculated using someone's educated guess based on previous observations or future estimations.

What describes empirical probability?

• Probability that can be calculated using theory, like flipping a coin, drawing a card, or rolling a die.

• Probability that can be calculated once an experiment has been done that has provided resulting data.

• Probability that can be calculated using someone's educated guess based on previous observations or future estimations.

What describes subjective probability?

• Probability that can be calculated using theory, like flipping a coin, drawing a card, or rolling a die.

• Probability that can be calculated once an experiment has been done that has provided resulting data.

• Probability that can be calculated using someone's educated guess based on previous observations or future estimations.

Neil tossed a 6-sided die 90 times. The results of his tosses are recorded in the table below: Which number has the experimental probability of 13/90?

• 1

• 2

• 3

• 4

• 5

What is the experimental probability of the spinner landing on a section that is green or red ?

• 5/10

• 1/2

• 2/5

• 1/5

If the spinner was spun 50 times and landed on 11 fifteen times, which statement is true?

• The experimental probability of landing on 11 is 1/8 while the theoretical probability of landing on 11 is 3/10

• The theoretical probability of landing on 11 is 12.5% while the experimental probability of landing on 11 is 30%

• The experimental probability of landing on 11 is less than the theoretical probability of landing on 11

• The theoretical probability of landing on 11 is equal to the experimental probability of landing on 11
