Total number of marbles in the bag =20
Number of blue marbles =4
Now we just want two blue marbles out of four.
Probability of taking out first marble which is blue =4/20
Now after we took out one blue marble , number of blue marbles left are 3.
Probability of taking out second marble which is blue =3/20
Total probability = 4/20 *3/20 = 12/400
So probability of taking out two blue marbles is 0.03 or 12/400.
The volume of one die is the edge to the power of 3:
![V=0.62^3in^{3^{}}.](https://tex.z-dn.net/?f=V%3D0.62%5E3in%5E%7B3%5E%7B%7D%7D.)
The total volume is five times the above volume:
![5V=1.19164in^3.](https://tex.z-dn.net/?f=5V%3D1.19164in%5E3.)
