**Hint:**

**19. What is the (approximate) probability that Die1+Die2+Die3=10?**

**20. What is the (approximate) probability that Die1+Die2+Die3>10?**

**21. What is the (approximate) probability that Die1+Die2>9? Careful: You need to create another column (and histogram) based on the first two dice or to argue directly by listing all possible outcomes!**
