Hmm. Could you explain,please?

- anonymous

uhm. let me read that again.

- anonymous

how did u get /31?

- anonymous

I added together all of the numbers and then took the number of reds and put it over that and simply reduced it. But I'm not sure I did it right because of the way that the question was asked. Oh and @zupster 6+8+5+9+2=30 not 25.

- anonymous

Thanks.

- anonymous

You're welcome(: idk If I helped or not.

- anonymous

I think you did:)

- anonymous

Thank you.

- anonymous

No problem :D ♥

- anonymous

:)

- anonymous

wait, mitt

- anonymous

i have a question.

- anonymous

I still need to pee ._. lol

- anonymous

do you know what it means by 'without replacing the other candy'?

- anonymous

then, perhaps it's 10 over 30, which would mean that it would be 1/3

- anonymous

hmmm....

- anonymous

The probability of selecting red is 9 / 30. The probability of selecting red for second time is 8 / 29.

- anonymous

So what is the answer?

- anonymous

8 / 29?

- anonymous

No.

- anonymous

Oh.

- anonymous

Sorry, you're on your own.

- anonymous

Hmm.

- anonymous

How is the probability the second time 8/29? you took away two candies didnt you?

- anonymous

That doesnt seem right..

- anonymous

No, it is asking what is the probability of selecting 2 red ones.

- anonymous

On part A i got 1/90

- anonymous

maybe that has something to do w/it?

- anonymous

I can doublr check this with a teacher if you want.

- anonymous

Thats okay. :)

- anonymous

I'm doing it anyway :P I dont want you to have the wrong answer c:

- anonymous

Okay.:)

- anonymous

A) \[\frac{ 2 }{ 30 }=\frac{ 1 }{ 15 } purple\]
\[\frac{ 5 }{30}=\frac{ 1 }{ 6 } orange\]
\[\frac{ 1 }{ 15 }•\frac{ 1 }{ 6 }=\frac{ 1 }{ 90 }\]
Good job(:
B) \[\frac{ 1 }{ 15 }•\frac{ 9 }{ 29 }=\frac{ 3 }{ 145 }\]
Do you understand? :o
