suppose we roll a very unbalance die: it has Probability 3/2 that is 1 show, and the probability of each of the other numbers 2 through 6 showing is 1/20. (check that there add up to 1.) let X represent the numbers that shows when we roll this die.
-compute the mean and standard deviation for X
-compute the actual Prob. P(mu-k sigma

Question

suppose we roll a very unbalance die: it has Probability 3/2 that is 1 show, and the probability of each of the other numbers 2 through 6 showing is 1/20. (check that there add up to 1.) let X represent the numbers that shows when we roll this die. 
-compute the mean and standard deviation for X 
-compute the actual Prob. P(mu-k sigma< X< mu+k sigma) for k=1,2,3.

anonymous · Answer

$$P(\mu - k \sigma< X< \mu - k \sigma)$$

Well, let's set up a probability model, do you know what that is?

nfcfox · Answer

@Andresfon12 dude if ur not gonna stay here close the fking question

anonymous · Answer

sorry i was afk for minute reading @nfcfox

nfcfox · Answer

@Andresfon12 ok well do u still want help?

anonymous · Answer

sure

nfcfox · Answer

do u know how to set up a probability model?

anonymous · Answer

k 1
P(mu - 1 sigm <X < mu mu +1 sigma)

nfcfox · Answer

this is a basic stats course right?

anonymous · Answer

yes is probability and statistic

nfcfox · Answer

ok well i will draw the probability model out, idk what the mu-1(sigma) but i can pretty much answer the first 2

anonymous · Answer

ok

nfcfox · Answer

wait so the probability of 1 is 3/2??? what

anonymous · Answer

mistype is  3/4

nfcfox · Answer

ok
