When a spinner with three colours (Fig. 3.5) is rotated, which colour has more chance to show up with an arrow than the others?

Solution:

Given, a spinner with three colours is rotated.

The figure represents a spinner with three colours R, B and Y.

We have to find which colour has more chance to show up with an arrow than the others.

From the figure,

We observe that the spinner is in the shape of a circle.

Colour Y occupies a region in the shape of a semicircle.

While the colours R and B combined together occupies other half of the circle.

The colour Y occupies more space than other two colours.

Therefore, the colour Y has more chance to show up with an arrow.
