Use it to find the probabilities. \(\displaystyle \begin{array}{c|c|c|c|c}\text{place}&\text{owns home}&\text{owns condo}&\text{rents}&\text{Total}\\ \hline\text{city}&20&100&180&300\\ \text{suburb}&120&45&60&225\\ \text{rural}&95&25&5&125\\ \hline\text{}&235&170&245&650\end{array}\) a.)What is the probability that the household lives in a suburb and owns a condo? Click to expand... \(\displaystyle \frac{120}{650}=\frac{12}{65}\) d.)What is the probability that the household owns a home given that they live in a suburb? Click to expand... When we have a 'given that', find the 'owns home' column down to the 'lives in a suburb' row and go across to the total. \(\displaystyle \frac{120}{225}=\frac{8}{15}\) See?.
