Answer 5

For the first question ^^

Answer 6

@hartnn

Answer 7

So for the first one it would be c?

Answer 8

I think..I'm not sure.

Answer 9

35 C 4
or
35*34*33*32
is correct :)

Answer 10

Oh, okay. Thanks @hartnn

So yes, C is correct.. @Pamela16

Answer 11

Thank you! do you think you could help with the last one

Answer 12

I can try.

Answer 13

Take your time :)

Answer 14

i'll let iGreen try :)

Answer 15

Okay

Answer 16

Well, if all the letters were different we could just go \(5 \times 4 \times 3 \times 2 \times 1\)..but there are two E's here so if we did \(5 \times 4 \times 3 \times 2 \times 1\) we will have combinations that are the same.

Answer 17

good start :)

Answer 18

Okay so that would = 120

Answer 19

No, I just said we can't do that.. out of those 120 combinations there will be some that are the same because we have two of the same letter..E.

Answer 20

Oh okay I apoligize

Answer 21

Okay, I'll just leave this to @hartnn to solve..lol. I have no idea where to go from there.

Answer 22

and then how would you eliminate duplicates ?

Answer 23

I don't know. ^^

Answer 24

I never learned how to do this stuff..lol.

Answer 25

Oh okay :) lol

Answer 26

let me give you examples, so that you get it easily :)

abcd ---> 4!

aabc ----> 4!/2!

abcde --->5!
aabcd --->5!/2!

aaabc---->5!/3!

aaabb ---->5!/(3!2!)

see the pattern ? :)

Answer 27

Kind of..

Answer 28

Im honestly thinking its a or c im maybe wrong?

Answer 29

cheer is like
aabcd

Answer 30

Ohhh!

Answer 31

And for aabcd we use 5!/2!..

Answer 32

So that's \(\dfrac{5 \times 4 \times 3 \times 2 \times 1}{2 \times 1}\)?

Answer 33

@hartnn

Answer 34

My session is about to run out could someone tell me the answer?

Answer 35

I believe that's it.. just multiply 5 x 4 x 3 x 2 x 1, and then divide it by 2 x 1.

Answer 36

You already found out that 5 x 4 x 3 x 2 x 1 is 120..so divide that by 2..what do you get? @Pamela16

Answer 37

60

Answer 38

Yep!

Answer 39

I think that's your answer.

Answer 40

60 it is :)
