Answer 1

The mean number of the children is 1.2

Explanation:

Given

Children: 0, 1, 2, 1, 2

Required

Determine the Mean number

The mean of a set is calculated as follows;

`Mean = (\sum x)/(n)`

Where x is the given set and n is the number of sets

In this case, n = 5 children

Hence;

`Mean = (0 + 1 + 2 + 1 + 2)/(5)`

`Mean = (6)/(5)`

`Mean = 1.2`

Hence, the mean number of the children is 1.2
