Q.21. A game consists of spinning an arrow which comes to rest pointing at one of the regions (1, 2, or 3) (See Figure). Are the outcomes 1, 2 and 3 equally likely to occur? Give reasons.

1 and 2 have probablity 1/4 
3 has 1/2

we have a circle, so the total angle will be 360?.
now area 1 and 2 contains 90? each and area 3 contains 180?.
P(area1)=P(area2)=90/360=1/4
and P(area3)=180/360= 1/2
so it is not equally divided!
