Best ResponseYou've already chosen the best response.1actually i got a different answer, we know this much 80% = married 75 % = married and work 5% = married and do not work from this we know that out of the 80% of the people, only 5% do not have a job. so now let look at the remaining 20% of non married people

Best ResponseYou've already chosen the best response.1we know this much 5% = people who arent married and do not work so far this is all be know from the info provided but the question doesnt mention anything about the remaining 15% but, we can reason out that the 15% much be people who are not married but work there fore 15% = not married but work

Best ResponseYou've already chosen the best response.1finally, out of the 80% of married people, only 5% do not have jobs and out of the 20% of single people only 5% do not have job. to conclude, there are a total of 10% of people that do not have jobs, 10% is ur answer

Best ResponseYou've already chosen the best response.0But the problem says Married: 80% (of the total) With work: 75% (of the married, so this is 75% of 80, so it would be a 60% of the total) Without a work: 5% (of the total, so itwould be 25% of a 20%) Single: 20%

Best ResponseYou've already chosen the best response.0Ok, perfect, so a 10% has no work

Best ResponseYou've already chosen the best response.0But the 75% apply to the married people, so it is 75% of 80%, (60)

Best ResponseYou've already chosen the best response.1ok and the 5% does not have a work and are not marrid, is that 5% of 100%? or something else?

Best ResponseYou've already chosen the best response.1the quesiton doesnt specify if that 5% is of the 100% or the remaining 20%

Best ResponseYou've already chosen the best response.0"Finally, 5% are not married and neither have a work" I think it is of the 100%

Best ResponseYou've already chosen the best response.1i agree with you that it's 75% of 80%, ill change that now, but before i do, i would think 5% of 100% as well

Best ResponseYou've already chosen the best response.1yea i think it's 25% as well, sry for mis reading the question

Best ResponseYou've already chosen the best response.0The hard question is: if one person has a work, which is the probability of him being married

Best ResponseYou've already chosen the best response.1im not familiar with that equation, but ik you dont need it, it can be reasoned out

Best ResponseYou've already chosen the best response.0P(A)=3/4 (probability of being married P(B)= 3/4 (probability of having a job)

Best ResponseYou've already chosen the best response.1id say 60% are married and work, 15% arnt married but work. there fore we find 60/75 x 100 and that should give us our answer

Best ResponseYou've already chosen the best response.0Can you explain me again the logic? You want to calculate the 75% of the 60%, but why?

HawkCrimson

Best ResponseYou've already chosen the best response.1kk, i did it in a calculus way though xD but u seem smart enough to understadn it :) Let x = total number of people y = 75% of x (number of people working) and let z = 60% of x (number of people married and working) therefore z/y times 100 = the percentage of married and working compared to just working)

HawkCrimson

Best ResponseYou've already chosen the best response.1therefore z/y of 100 = 60% of x / 75% of x times 100 the x cancels so 60/100 / 75/100 times 100 60/75 times 100

Best ResponseYou've already chosen the best response.0The last question is what percentage is married inside the ones that does not have a job

osanseviero

Best ResponseYou've already chosen the best response.0So... 75100 x80 Can that apply? 80*75 divded by 100

Best ResponseYou've already chosen the best response.0x=total y=75% of x z=25% of x

HawkCrimson

Best ResponseYou've already chosen the best response.1in this case x = total y = 25% of x (people with no jobs) z = 20% of x (people who are married and do not have a job) z/y times 100 = 20/25 times 100 = 80%.. wait, again? O.o

Best ResponseYou've already chosen the best response.1kk, but still id be nice to learn another way cause this way is tedious. probably there is an equation that would of made all of this simple
