Best ResponseYou've already chosen the best response.0okay, what is the number of houses between 3 and 4 years old?

anonymous

Best ResponseYou've already chosen the best response.0okay. so what is the probability that any one of the 1580 houses will be chosen, given that there are 7520 total houses?

Best ResponseYou've already chosen the best response.0do you know anything about probability and sample sets?

Best ResponseYou've already chosen the best response.0then why are you doing this problem if you don't know probability?

Best ResponseYou've already chosen the best response.0because i need to learn how

Best ResponseYou've already chosen the best response.0okay. then I will explain probability to you. suppose you have a dice. you roll it. what are the chances that it will land on the number 4?

anonymous

Best ResponseYou've already chosen the best response.0yes. so there are one in 6 chances that the dice will roll 4. what are the chances that the dice will roll an even number?

anonymous

Best ResponseYou've already chosen the best response.0right. so what were are calling chances, are formally called probability. probability of outcome that you want = set of the outcomes you want/set of all outcomes

anonymous

Best ResponseYou've already chosen the best response.0so set of outcomes you want for the dice to roll even number is {2,4,6}. set of all outcomes is {1,2,3,4,5,6}.

Best ResponseYou've already chosen the best response.0ok i understand...so in relation to that problem

anonymous

Best ResponseYou've already chosen the best response.0so what is the set of outcomes you want?

anonymous

Best ResponseYou've already chosen the best response.0I dont know what that means

anonymous

Best ResponseYou've already chosen the best response.0okay in the dice problem, the set of outcomes you wanted was of size 3. the set of all outcomes was of size 6. so the probability of even number was 3/6 or 1/2 correct?

Best ResponseYou've already chosen the best response.0so what is the desired outcome in your problem?

anonymous

Best ResponseYou've already chosen the best response.0I dont know how to figure that out

anonymous

Best ResponseYou've already chosen the best response.0its given in the problem. the desired outcome is you choose a house 34 years old. so how many houses are 34 years old?

anonymous

Best ResponseYou've already chosen the best response.0and what is the set of all outcomes?

anonymous

Best ResponseYou've already chosen the best response.0right. you have to choose one house and its set is all the houses in that area. So the set size is 7520. so what is the probability that you choose one of the 1580 houses?

anonymous

Best ResponseYou've already chosen the best response.07520/1580...then simplify?

anonymous

Best ResponseYou've already chosen the best response.0no no. probability is the set of desired/ total. you have done total/desired.

anonymous

Best ResponseYou've already chosen the best response.0probability cannot be greater than 1.

anonymous

Best ResponseYou've already chosen the best response.0soo 1580/7520 then simplify

anonymous

Best ResponseYou've already chosen the best response.0im sure you did the calculation right.

anonymous

Best ResponseYou've already chosen the best response.0now, for the other part. what are the odds that you choose a house less than 9 years old?

anonymous

Best ResponseYou've already chosen the best response.0what is the desired outcome?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i know that it is some number to 75

anonymous

Best ResponseYou've already chosen the best response.0okay so desired outcome/total outcome = ?

anonymous

Best ResponseYou've already chosen the best response.0ok. you have your answers.

anonymous

Best ResponseYou've already chosen the best response.0so the answer is what to 75?

anonymous

Best ResponseYou've already chosen the best response.0what to 75? what does that mean?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0because in my problem it says what are the odds the house is less then 9 years old....it has a fill in the blank of ? number to 75

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh okay. then the number you are looking for is 0.8 times 75

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0your probability is 0.8. it can be expressed as 4/5 or 80/100 or 60/75 in your case.
