## Loser66 one year ago Find the total ways in which 6 objective type questions can be answered when each question has 5 choices. Please, hep

1. Loser66

another one: There are 5 multiple choice questions in an exam. How many sequences of answers are possible if the first question has 3 choices, next two have 4 choices and the last two have 5 choices.

2. Loser66

Among the problems, which quantity is greater?

3. Loser66

@zepdrix

4. mathmath333

is $$\large 5^{6}$$ the answer for 1st one

5. Loser66

I think so!! Just want to make sure it is right.

6. Loser66

$$\left(\begin{matrix}5\\1\end{matrix}\right)$$ for each object and we have 6 objects, That gives us $$\left(\begin{matrix}5\\1\end{matrix}\right)^6= 5^6$$

7. Loser66

How about the second one? Actually, I don't like statistics and probability. I took the course and got very few knowledge :(

8. mathmath333

for the second one i think it is = $$\large 3\times 4^{2}\times 5^{2}$$
