@CliffSedge
I have a table here that I don't quite understand
x 0 1 2 3 4 5
P(x) 0.237 0.396 0.264 0.088 0.015 0.001
x= # of prisons out of 5 on parole who become repeat offenders.
What is P(x)? and why does it add up to 1?

Best ResponseYou've already chosen the best response.1If they add up to 1, those could be probabilities or proportions.

Best ResponseYou've already chosen the best response.0Criminal Justice: Parole USA Today reported that approximately 25% of all state prison inmates released on parole become repeat offenders while on parole. Suppose the parole board is examining five prisoners up for parole. Let x= number of prisoners out of five on parole who become repeat offenders. The methods of Section 5.2 can be used to compute the probability assignments for the x distribution.

Best ResponseYou've already chosen the best response.0so x from 0 to 5 are not "the prisoners"

Best ResponseYou've already chosen the best response.0I guess I don't understand what x is...sigh

Best ResponseYou've already chosen the best response.1It is a little strangely worded, but it says that x is number out of 5, so x itself is a proportion.

Best ResponseYou've already chosen the best response.1e.g. x=3 means 3 out of the 5 prisoners up for parole will be repeat offenders.

Best ResponseYou've already chosen the best response.0\[\frac05\] why is there are chance for repeat offense?

Best ResponseYou've already chosen the best response.1*shrug* that's just what they are measuring here.

Best ResponseYou've already chosen the best response.0so when no one is on parole the probability or reoffending is 0.237? That's what they're trying to tell me?

Best ResponseYou've already chosen the best response.1No, it's saying that for every 5 prisoners out on parole the probability that 0 of them will offend again is 0.237

Best ResponseYou've already chosen the best response.05 are out on parole at all time I guess

Best ResponseYou've already chosen the best response.1It's just an average 'per 5' basis. There could be 100 parolees, so x=3 means 60 out of 100.

Best ResponseYou've already chosen the best response.0the probability that 5/5 parolees will reoffend is very slim? highly unlikely?

Best ResponseYou've already chosen the best response.1Yeah, 0.001 is pretty low, 1in1,000 chance, but if there are 5,000 parolees, then that's practically a sure thing.

Best ResponseYou've already chosen the best response.1(Practically a sure thing to get 5 out of 5,000, not 5,000 out of 5,000 that is)

Best ResponseYou've already chosen the best response.0Yep makes sense. Thank you once again!
