We need to use product rule because the first event is picking the mathematics major and second event is picking the computer science major
![$$21\times325=6825$$](https://tex.z-dn.net/?f=%24%2421%5Ctimes325%3D6825%24%24)
We need to use sum rule because the first event is picking OR mathematics major and second event is picking the computer science major
![$$21+325=346$$](https://tex.z-dn.net/?f=%24%2421%2B325%3D346%24%24)
