  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

spare ermine
#

1 a) i got 50

#

1 b) i got 26

#

but

#

im pretty sure its wrong

shadow condor
#

I didn't ask what you got, I asked what you did.

spare ermine
#

for a part

#

5/14 *140

shadow condor
#

Why?

spare ermine
#

i multiplyed the

#

probability

#

wid

#

the

#

no. of times

shadow condor
#

Why?

spare ermine
#

cuz

#

i wanted to find the

#

probability of the no. of times

shadow condor
#

No.

#

You wanted to find the expectation.

spare ermine
#

ya

#

thats the word

#

so

#

how do i do

#

b

#

part

shadow condor
#

You didn't do a right.

spare ermine
#

wts the rite answer then?

shadow condor
#

Hmm.

spare ermine
#

bro

#

u gonna help me or not?

#

.

#

.

shadow condor
#

I'm trying to.

spare ermine
#

im pretty sure its right

shadow condor
spare ermine
#

then how is it supposed to be done?

shadow condor
#

Here's how it works.

#

What's the probability of getting zero greens?

spare ermine
#

0/5?

shadow condor
#

No.

#

And that answer doesn't inspire confidence that you'll be able to understand the full explanation.

spare ermine
#

ik

#

im failing tmr

spare ermine
shadow condor
#

Okay, let's try a simpler case.

#

A coin.

#

If you flip a coin ten times, what's the probability of getting exactly four heads?

#

Wait, no.

#

Sorry, I haven't had breakfast yet.

spare ermine
#

wts wrong?

shadow condor
#

I'm actually probably as unequipped to explain this to you as you are to understand it at the moment.

spare ermine
#

oh wait

spare ermine
shadow condor
spare ermine
#

i didnt say it was

shadow condor
#

...you did. You said it was something I did.

spare ermine
spare ermine
#

wait

#

wtever

spare ermine
shadow condor
# spare ermine wait wts the answer to this

The answer is actually 50, and it's possible that you calculated it correctly, but I'm confused by the problem because the way you did it is not the way to calculate it in general, and so I'm confused because I don't know if this is a special case where that works, or what.

spare ermine
#

how is it 50?

#

wat other GENERAL way is there to do?

#

how on gods green earth is it 50

#

u better not ghost me now

#

@shadow condor

shadow condor
#

Be. Patient.

#

Or I will leave.

spare ermine
#

fine

#

take ur time

#

ig

#

not like i have to prepare for my midterm which is tmr

shadow condor
#

$\sum_{n=0}^{140} n * \frac{140!}{n! (140 - n)!} * \left( \frac{5}{14} \right)^n * \left( \frac{9}{14} \right)^{140 - n}$

how so?

spare ermine
#

y 9?

shadow condor
#

...because read the problem.

#

You're adding these discs.

spare ermine
#

wts the final answer?

#

i got 26

deft quail
#

oh lol

spare ermine
#

is it wrong or rite?

deft quail
#

i didnt read the problem

#

mbmb

#

so now total disks = 23+x

shadow condor
#

@spare ermine I'm sorry for confusing you, I think in the specific case you were working you did actually calculate the expectation correctly.

#

I'm not sure, and that bugs me, but you got the correct final answer.

deft quail
#

and $\frac{14}{23+x}=\frac{2}{7}$
