Basic probability question for you

Alpi Gusto

2/21/18 12:45pm

66%?

JuicyJam

2/21/18 12:46pm

Yes

Great38

2/21/18 12:50pm

50/50--it either is or it isn't.

Carnac

Here’s why I ask

Alpi Gusto

2/21/18 12:50pm

Are you a student at BYU or Utah?

Carnac

She is solving the probability that the first is red AND the second is blue

Great38

2/21/18 12:55pm

The whole class was asking why it shouldn’t be 2/3

Alpi Gusto

2/21/18 12:58pm

if the question you posted is verbatim from your notes

The Shazad

2/21/18 12:59pm

In that case, 2/3. It's a conditional probability question.

Great38

2/21/18 1:02pm

That is a different question

Doesn't sound like you are answering the same question to me.

JuicyJam

2/21/18 12:56pm

Right. She answered a different question than what was on the notes

Alpi Gusto

So you select the two balls at the same time or one at a time?

Big Wally D

2/21/18 12:52pm

One at a time

Alpi Gusto

2/21/18 12:52pm

I agree with Juicy and their question is worded wrong if the professor

Big Wally D

2/21/18 12:57pm

^^THIS^^ The key to this problem is WHEN...

jomo

2/21/18 12:58pm

Yeah. I understood you saying you pull two out and then look and see one is

jcase16byu

is this like Let's Make a Deal where the % changes based on info from 1st choice

byujag

2/21/18 12:55pm

Not really, that would require that they pull a ball out of the bag and show

Maybe this kid was right after all...

Great38

Same professor here too

Alpi Gusto

2/21/18 1:09pm

What class is this?

JuicyJam

2/21/18 1:42pm

Stats 1040

Alpi Gusto

2/21/18 1:55pm

I work with a few statisticians from USU, maybe I should give them a hard time.

Great38

2/21/18 2:01pm

Go for it. She’s a grad student too
