hmm, I think its $3\over15$ but I'm not exactly possitive.

uhm. let me read that again.

how did u get /31?

7. Kitt020912 Group Title

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.

Thanks.

9. Kitt020912 Group Title

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

I think you did:)

Thank you.

No problem :D ♥

:)

wait, mitt

i have a question.

16. Kitt020912 Group Title

I still need to pee ._. lol

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

18. Kitt020912 Group Title

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

hmmm....

20. micahwood50 Group Title

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

8 / 29?

23. micahwood50 Group Title

No.

Oh.

25. micahwood50 Group Title

26. Kitt020912 Group Title

Hmm.

27. Kitt020912 Group Title

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

28. Kitt020912 Group Title

That doesnt seem right..

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

On part A i got 1/90

maybe that has something to do w/it?

32. Kitt020912 Group Title

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

Thats okay. :)

34. Kitt020912 Group Title

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

Okay.:)

36. Kitt020912 Group Title

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

Thanks, do u simplify?

@Kitt020912
