Solution
The correct option is C 70
We need to find the number of families with atleast one child,i.e, Number of families with 1 child or 2 children.
We can see that,
The number of families with 1 child = 30
The number of families with 2 children = 40
Therefore, 70 families have atleast one child.
(This is an example of empirical probability because an actual observation was carried out by collecting data through a survey. The survey to find the number of children in each family is the experiment and the data given in the table represents the outcomes.)
