numbers on spinner: 1, 4, 7, 10, 13, 16, 19, 22, 25, 28
If this spinner is to be spun once, how likely will it stop on a multiple of 9.
a. unlikely
b. impossible
c. certain
d. less likely than not
b. impossible
A multiple of 9 is any number that can be divided evenly by 9. None of the numbers on the spinner are multiples of 9 (9, 18, 27). Therefore, it is impossible for the spinner to stop on a multiple of 9.
