Question:
You spin a spinner that has 12 equal-sized sections numbered 1 to 12. Find the theoretical probability of landing on the given section(s) of the spinner.
1. P(6) 1/12
2. P(lodd number)
3. P(greater than 8)
4. P(less than 9)
5. P(multiple of 3)
6. P(multiple of 5)
7. P(greater than 10)
8. P(less than 4)
9. P(not 1)
Given there are 12 numbers equally.
1. P(6) = 1/12 one out of twelve.
2. P(lodd number) = 6/12 = 1/2 :
1, 3, 5, 7, 9, 11.
4. P(less than 9) = 8/12 = 3/4 :
1, 2, 3, 4, 5, 6, 7, 8
5. P(multiple of 3) = 4/12 = 1/3 :
3, 6, 9, 12
7. P(greater than 10) = 2/12 = 1/6 : 11, 12
8. P(less than 4) = 3/12 = 1/4 :
1, 2, 3,
