We can compare the two data by their mean

Neighbourhood Q = \frac{2+5+4+3+2+5+3+6+5}{9}= \frac{35}{9}=3.9
Neighbourhood S = \frac{2+3+2+3+7+2+3+3+2}{9}= \frac{27}{9}=3

Neighbourhood Q has larger mean than Neighbourhood S so it appears Neighbourhood Q has larger family size.

Number of ways it can happen = 27;

Total number of outcomes = 6*6 = 36;



Probability of an event happening = Number of ways it can happen<span><span> / </span>Total number of outcomes => Probability = 27/36 = 0.75;</span>
