On the first draw, there are a total of 24 balls. On the second draw, there will be left with 23 (24-1) balls hence, the denominator changes.

Depending on the colour of ball you drew on the first time, it’ll affect the number of ball of the same colour drawn on the second time.

Hope this helps :)
