Question

A game consists of spining an arrow which comes to rest pointing at one of regions (1,2 or 3) (see figure). Are the outcomes 1,2 and 3 equally likely to occur? Give reason

Answer 1

No, the outcomes are not equally likely, because 3 contains half part of the total region, so it more likely than 1 and 2, since 1 and 2, each contains half part of remaining part of the region.
