Basically, I was referring to that Yellow highlighted portion. Why multiply with "Total Number of Horses" each time?
Isn't it should be like this below?
Average = (16% * 0 + 8% * 1 + 24% * 2 + 20% * 3 + 20% * 4 + 12% * 5 or more) / Total Number of Houses
To get total number of houses with 0 Televisions you have to do 16% multiplied by number of houses. Lets understand using below example
Total number of students = 100
% of boys in class is 20%
If I ask you the actual number of boys then will we say 20% or 20% of Total
We will say 20% of Total = \(\frac{20}{100}\) * 100 = 20 boys
Hope this helps!
