a = 2/3

b = 1536

c = 8/25

d = -16

e = 3*2^(1/2) which is approxomately 4.2

the correct answer is D C A E B

\(\binom{n}{k} = \binom{n - 2}{k} + \binom{n - 2}{k - 1} + \binom{n - 1}{k} + \binom{n - 1}{k - 1} + \binom{n}{k - 1} + \binom{n}{k + 1}\)

Try using pascal's Identity which states that \(\binom{n}{k} = \binom{n - 1}{k} + \binom{n - 1}{k - 1}\)

hopefully this helps :)

please include the numbers in your problem and take a little time to format it,

its pretty odvious that you are copy and pasting this from a website but take a second to give us the actual problem if you want a real solution

probability is defined by the 

amount of times when it is true/ total amount of times (or false + true in most cases)

the total is 6! or 6*5*4*3*2*1

since we have the pair's of socks over 3 days we take every other integer to multiply

6*4*2

so if we take 6,4,2 out of the denominater

\(\frac{1}{5*3*1}\)

since 1*x = x we can take this out of the equation

5*3 = 15

the solution is \(\frac 1 {15}\)

This goes to a russian video uploading website that I can't open...

Looks like it was not properly copied off of a latex using website

Looks like it was copied from a website, but you are in luck (probably) this problem has probably already been solved

I can't see a diagram, but to solve a parrellogram but I suspect that they are right triangles inside of the parrellogram so the side of the rectangle makes up the height of the parrellogram

example:

Is this correct?

I will pin this, if this answer is wrong I will take a shot at it
