To find how many ways a student can answer the given questions on the test if the student answers every question :</h3>
Solving this by product rule
Product rule :
<u>If one event can occur in m ways and a second event occur in n ways, the number of ways of two events can occur in sequence is then m.n</u>
From the given the event of choosing the answer of each question having 4 options is given by
The 1st event of picking the answer of the 1st question=4 ,
2nd event of picking the answer of the 2nd question=4 ,
3rd event of picking the answer of the 3rd question=4
,....,
10th event of picking the answer of the 10th question=4.
It can be written as by using the product rule
![=4.4.4.4.4.4.4.4.4.4](https://tex.z-dn.net/?f=%3D4.4.4.4.4.4.4.4.4.4)
![=4^{10}](https://tex.z-dn.net/?f=%3D4%5E%7B10%7D)
![=1048576](https://tex.z-dn.net/?f=%3D1048576)
<h3>∴ there are 1048576 ways a student can answer the questions on the test if the student answers every question.</h3>
