Explanation:
Two boxes contains the following pieces of chalk of the same size.
Red = 2
Yellow = 1
Green = 4
White = 3
Blue = 2
Each box contains = 2 + 1 + 4 + 3 + 2 = 12 pieces of chalk of the same size.
There are total pieces of chalks are 12 and white chalks are 3 in each box.
If one piece of chalk will be randomly selected from each box.
The probability of first box that piece will be white =

The probability of second box =

Therefore, P =
