Question

In the accompanying diagram a fair spinner is placed at the centre o of the circle.Diameter AOB and radius OC divide the circle into three rigions labelled X, Y and Z.ROC - 45. What is the probability that the spinner will land in the region X?(See Fig. 16.10)​

Answer 1

probability that the spinner will land in the region X = 3/8

Step-by-step explanation:

Let say Area of Circle = A

Area of Y  = ( 180 /360) Area of Circle  = A/2

Area of  Z  = (45/360) * Area of Circle = A/8

Area of X  = A -  A/2 - A/8

=> area of X = ( 8 - 4 - 1)A/8  = 3A/8

the probability that the spinner will land in the region X = Area of X / Area of Circle

= (3A/8) /A

= 3/8

probability that the spinner will land in the region X = 3/8
