Answer: B ) 2.5

Step-by-step explanation:

Let x be the number of pets and f represents the frequency .

The formula to find average (mean) is given by :-

$\overline{x}=\dfrac{\sum fx}{\sum f}$

Then for the given data, the average number of pets per house is given by :-

$\overline{x}=\dfrac{0\times2+1\times1+2\times8+3\times10+4\times4}{2+1+8+10+4}\\\\\Rightarrow\ \overline{x}=\dfrac{63}{25}=2.52\approx2.5$

Hence, the average number of pets per house =2.5
