Question

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

Answer 1

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