statistical distribution

raw egret
#

If you want to find probability less than 2 and more than or equal to minus 1 you add the probability of -1, 0 and 1

#

You don't add the probability of two because it has to be less than two

peak oracle
#

-1+1+0 =0?

raw egret
#

No those are the x values you add the probabilities

#

Probabilities can't be negative

peak oracle
#

So u would do 0.25+0
25+0.15???

#

Cause ik rhe answer is 0.6 from ms but I'm lost how they got to there

raw egret
#

Huh

#

You would do 2 alpha + 0.1

peak oracle
#

Wth is alpha

raw egret
#

The a

#

For the probability of -1,0

peak oracle
#

So 2×(1/4)?

#

Mayn maths is not for me

raw egret
#

Yes If that's what you found it to be

peak oracle
#

Why would u times it by 2 and add my 0.1 tho

raw egret
#

If it's confusing you do a table of x values and probabilities

peak oracle
#

Alright ok

raw egret
#

Send a pic when you done it

peak oracle
#

Ok

#

What I'm doing feels incredibly wrong

raw egret
#

Yo what is that

peak oracle
#

Bro I ain't got a clue

#

Like I'm deadass lost on this question

#

The other ones I understand cause it had like idk K in it or something but this has none so I'm like what do u even do

raw egret
#

I meant a table like this

#

Now if you want the probability that it asks in the question you add -1 0 and 1

#

Add those 3 probabliities together and u get 0.6

#

Part c uses a decimal to trick you but you just add all probabilities greater than - 2.3 so just add all the probabilities from -2 to 2

OHHHH TYYY THIS MAKES SO MUCH SENSE NOW THANK U I UNDERSTAND
