Answer 2

3) 1

is that the answer? :P

Answer 3

yee tso i think thas correct

Answer 4

Nope :)

Answer 5

aww

Answer 6

when you have 4 answer choices, there is a 1/4 probability

there are two 1/4 answer choices which makes the probability 1/2

and there is one 1/2 answer choice which makes 1 the answer? :P

Answer 7

Nope :)

Answer 8

its D ;)

Answer 9

wait A and D are same

Answer 10

maybe this has to do something with the ques xD
well since its not a multiple choice so neither A nor D is correct also 1 is not correct so i'd go with 1/2 ;)

Answer 11

Lol xD Nope

Answer 12

D:

Answer 13

the answer has to be E) none of the above I guess :P

Answer 14

Actually, yes, but there's a number TSO xD
If it's none of the options, which is it?

Answer 15

3/4 ? :)

Answer 16

25%? ;p

Answer 17

Why am I thinking that somehow this has to do WITH the option numbers.
This isn't laid out in A, B, C, D format but rather 1, 2, 3, 4.

Answer 18

Nope @Atsie

Answer 19

is the answer 0.25 ;p

Answer 20

LOL xD I was hoping no one saw that!

Answer 21

JADE, your losing your marbles! xDDD

Answer 22

they not choices they numbers ?

Answer 23

don't tell the solution rn tho! we're thinking

Answer 24

@Atsie they still didn't see it. oh my goodness xD

Answer 25

Welp, I'll just put my reply away xDD

Answer 26

Do you guys give up?

Answer 27

Why would we give up? We are the brightest of OS! We must find out!

Answer 28

Lol mhm, I totally believe that xD
@agent0smith

Answer 29

Its 1/3 i believe.
But thtas not an option xD

Answer 30

That is incorrect :)

Answer 31

okay so if the answer is 1/4 then it will mean that probability to choose 1/4 as the correct answer is 1/4
this is wrong because there are two 1/4s
and
probability of choosing 1/2 is 1/2 is also wrong because here total favorable outcomes =1 and total outcomes=3

now probability of choosing 1 can't be 1 cuz favorable outcomes =1 and total outcomes=3

and now probability of choosing 0 is 0 cuz favorable outcomes=0 and total outcomes=3 :)

Answer 32

So what does that mean?

Answer 33

wait ima make some edits in that^^

Answer 34

b

Answer 35

2)1/2

Answer 36

Nope :)

Answer 37

1)

Answer 38

Nope

Answer 39

qwerty, you got this!

Answer 40

3)

Answer 41

nope

Answer 42

okay so \(probability=\large\frac{total~favorable~outcomes}{total~outcomes}\)

->if the answer is 1/4 then it will mean that probability to choose 1/4 as the correct answer is 1/4
this is wrong cuz total favorable outcomes= 2 and total outcomes=3 so apply that formula and we get that probability to chose 1/4 as correct answer is 2/3 which is contradicting!

->if probability of choosing 1/2 as correct is 1/2 is also wrong because here total favorable outcomes =1 and total outcomes=3 (again contradiction)

now probability of choosing 1 can't be 1 cuz favorable outcomes =1 and total outcomes=3 (again contradiction)

and now probability of choosing 0 is 0 cuz favorable outcomes=0 and total outcomes=3 :)

Answer 43

cody, read what we've discussed already
