The spinner is divided into 10 equal sections. A spinner divided into 10 equal sections labeled 1 through 10. Which event has theoretical probability of exactly One-fifth? Select three options. spinning a number less than 3 spinning a 4 or 5 spinning an odd number spinning a number greater than 8 spinning a number less than 8

The event that has theoretical probability of exactly One-fifth is A) spinning a number less than 3. B) spinning a 4 or 5. C) spinning a number greater than 8 Step-by-step explanation:  The spinner is divided into 10 which are labelled 1 to 10.  Therefore the possible outcomes are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. The total number of possible outcome is 10 Probability is gotten by dividing the number of events by total possible outcome. A) The probability of spinning a number less than 3. The numbers less than 3 are 1,2. Therefore the number of events is 2. P(Number less than 3) = number of events/total possible outcome = 2/10 = 1/5 B) The probability of spinning a 4 or 5. The probability of spinning a 4= P(4) = 1/10 The probability of spinning a 5= P(5) = 1/10 The probability of spinning a 4 or 5. = P(4 or 5) = P(4) + P(5) = 1/10 + 1/10= 2/10 = 1/5 C) The probability of spinning an odd number. The odd numbers are 1, 3, 5, 7, 9. Therefore the number of events is 5 P(odd numbers) = number of events/total possible outcome = 5/10 = 1/2 D) The probability of spinning a number greater than 8 The numbers greater than 8 are 9, 10. Therefore the number of events is 2. P(Number greater than 8) = number of events/total possible outcome = 2/10 = 1/5 E) The probability of spinning a number less than 8 The numbers less than 8 are 1, 2, 3, 4, 5 6, 7. Therefore the number of events is 7. P(Number less than 8) = number of events/total possible outcome = 7/10 =
