how did u get /31?
anonymous
  • 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
  • anonymous
do you know what it means by 'without replacing the other candy'?
anonymous
  • anonymous
then, perhaps it's 10 over 30, which would mean that it would be 1/3
anonymous
  • anonymous
hmmm....
anonymous
  • anonymous
The probability of selecting red is 9 / 30. The probability of selecting red for second time is 8 / 29.
anonymous
  • anonymous
So what is the answer?
anonymous
  • anonymous
8 / 29?
anonymous
  • anonymous
No.
anonymous
  • anonymous
Oh.
anonymous
  • anonymous
Sorry, you're on your own.
anonymous
  • anonymous
Hmm.
anonymous
  • anonymous
How is the probability the second time 8/29? you took away two candies didnt you?
anonymous
  • anonymous
That doesnt seem right..
anonymous
  • anonymous
No, it is asking what is the probability of selecting 2 red ones.
anonymous
  • anonymous
On part A i got 1/90
anonymous
  • anonymous
maybe that has something to do w/it?
anonymous
  • anonymous
I can doublr check this with a teacher if you want.
anonymous
  • anonymous
Thats okay. :)
anonymous
  • anonymous
I'm doing it anyway :P I dont want you to have the wrong answer c:
anonymous
  • anonymous
Okay.:)
anonymous
  • 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
