It can be explained

let in first two  balls you take is of different color i.e 1 white and 1 red ball

Third ball , whether you take  white or red ball you will have

two balls of same color.

if your third  ball is  red ball

then you will have 2 red balls and 1 white ball.

if your third   ball is white,

then you will have 2 white balls and 1 red balls.
