How many different ways can an after school club of 13 students line up?
maksim [4K]

Answer:

13! or 6227020800

Step-by-step explanation:

With no restrictions, we can figure out the answer to be 13! by the following analysis:

For the first position in line, there are 13 different students who could fill that spot. If we fill it and proceed to the next position in line, there are now only 12 students left who can fill it, since one is already in line. Then the next position only has 11 possibilities, and the next 10, and so on.

Multiplying all of this together gives us 13*12*11*10*9*8*7*6*5*4*3*2*1 or 13!

Shalnov [3]

Answer:

0.7429

Step-by-step explanation:

Given that  Of the 721 students at the college, 299 of them apply for loans when entering graduate school.

So p = proportion of students applying for loans = \frac{299}{721} =0.415

Each student is independent of the other and there are two outcomes

Hence out of 45 students the no of students who apply for loans say X is binomial with n =45 and p = 0.415

the probability that more than 16 of them apply for loans

=P(X>16)\\= \Sigma_{x=17} ^{45}  P(x)\\=\Sigma_{x=17} ^{45}(45Cx (0.415)^x (0.585)^{25-x} )

=0.7429
