The answer is 1, 5/12, and 2/3.
It is 1 because the event that it lands on a section must be 1.
It is 5/12 because we could pick any 5 sections and the event it would be one of them is 5/12.
It is 2/3 for the same logic as 5/12 because 2/3 = 8/12.
It is not 3/8 because you can not have a decimal of a possibility, that is not possible, and it is not 13/12 because you cannot have a higher probability than 1, since it is not possible for there to be 13 winning possibilities out of 12.
