igor_vitrenko [27]

Answer:

0.4625 or 46.25%

Step-by-step explanation:

The data for the percentage of contribution and the percentage of numbers from each suburb is presented in the table bellow:

$\begin{array}{ccc}&Contribution (C)&Number(N)\\Belle\ Mead&0.60&0.25\\Oak\ Hill&0.55&0.25\\Antioch&0.35&0.5\end{array}$

The probability that she gets a donation is given by the sum of the probabilities of getting a donation from each suburb weighed by their respective percentage of numbers of the list:

$P(C) = P(C_B)+P(C_O)+P(C_A)\\P(C) =0.6*0.25+0.55*0.25+0.35*0.5\\P(C) = 0.4625$

The probability that she gets a donation is 0.4625 or 46.25%.
