Question 1: A spinner is divided into 4 equal sectors numbered 1 to 4. What is the probability of spinning a 3?

Answer: 0.25

Question 2: If a spinner has 6 equal sectors numbered 1 to 6, what is the probability of spinning an even number?

Answer: 0.5

Question 3: Calculate the probability of not landing on the sector numbered 5 when spinning a 10-sector spinner numbered 1 to 10.

Answer: 0.9

Question 4: A spinner is divided into 3 red sectors, 2 blue sectors, and 5 yellow sectors. What is the probability of spinning a yellow sector?

Answer: 0.5

Question 5: Construct a spinner with 8 equal sectors, where 3 sectors are green, 2 are purple, and 3 are orange. What is the probability of landing on a purple sector?

Answer: 0.25

Question 6: A spinner has 5 equal sectors labeled A, B, C, D, and E. If the spinner is spun twice, what is the probability of landing on A both times?

Answer: 0.04

Question 7: A spinner with 8 equal sectors is spun. What is the probability of landing on either sector 1 or sector 2?

Answer: 0.25

Question 8: A spinner is divided into 12 equal parts, with 4 parts colored red, 4 blue, and 4 green. What is the probability of spinning green?

Answer: 0.3333

Question 9: A spinner has 6 sectors labeled 1 through 6. If the spinner is spun three times, what is the probability of getting a 4 each time?

Answer: 1/216

Question 10: A spinner with 10 equal sectors is spun. What is the probability of landing on a prime number?

Answer: 0.4

Question 11: Identify and correct the mistake in the following reasoning: 'The probability of landing on a red sector is 1/3, so the probability of landing on red twice in a row is 1/9.'

Answer: The mistake is that the probability of landing on red twice in a row should be (1/3) * (1/3) = 1/9, which is correct. The question is a trap; students should recognize the reasoning is actually correct or explain that the calculation is correct. Alternatively, if the initial assumption was incorrect, they should identify it.
