I need help with a few probability questions..Please help. Pictures included.

OpenStudy (anonymous):

OpenStudy (anonymous):

you got 9 bills total right?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Wait no

OpenStudy (anonymous):

probability you get a $5 is \[\frac{4}{9}\] then that bill is gone and you have 8 left

OpenStudy (anonymous):

probability you get a $10 is \(\frac{4}{8}=\frac{1}{4}\)

OpenStudy (anonymous):

I have 43 bills. The three 1s, the four 5s, the two 10s.

OpenStudy (anonymous):

multiply those numbers get \[\frac{4}{9}\times \frac{1}{4}=\frac{1}{9}\]

OpenStudy (anonymous):

lol you have maybe $43 but you have only 9 bills

OpenStudy (anonymous):

OHHHH. I understand what you mean now. Yeah, I get it now. I have nine bills

OpenStudy (anonymous):

ok so you want to start again or is the answer clear?

OpenStudy (anonymous):

I think it's clear

OpenStudy (anonymous):

Yes, it is. Thank you very much. Would you possibly help me with some more similar questions? :)

OpenStudy (anonymous):

sure if i can

OpenStudy (anonymous):

OpenStudy (anonymous):

how many letters?

OpenStudy (anonymous):

11

OpenStudy (anonymous):

k good how many consonants

OpenStudy (anonymous):

Ummm..5?

OpenStudy (anonymous):

i count 7

OpenStudy (anonymous):

Oh, I recounted. Seven it is.

OpenStudy (anonymous):

so first one is a consonant, \[\frac{7}{11}\] now there are 10 letters left, and 3 E's so \[\frac{3}{10}\] multiply get \[\frac{7}{11}\times \frac{3}{10}\]

OpenStudy (anonymous):

Alright...So the answer is 21/110?
