Question

The mean of the first five whole numbers is$\underline{}$

Answer 1

$$\begin{gathered} Firstfivewholenumbers=0,1,2,3,4 \\ Mean=\frac{Sumoftheobservation}{Numberofobservations} \\ Meanoffirst5wholenumbers=\frac{Sumofobservations}{Numberofobservations} \\ =\frac{0+1+2+3+4}{5} \\ =\frac{10}{2} \\ Dividebycommomfactorby2 \\ Meanoffirstfivewholenumbers=\frac{10÷5}{2÷2} \\ Therefore,Meanoffirstfivewholenumbers=2 \end{gathered}$$
