Explanation / Answer

you have to multiply the probabilities because is "and", you live and a household and is a rental and you have two children. If theres a exclusion like "you have three or two childrend" it will be a sum, but is not the case.

so you have

P(household)= 0.25

P(rental) = 4/10= 0.40

P(new york)= 0.06

P total= 0.25*0.06*0.40= 0.006
