In a locality, 1000 families were chosen at random and the following data was collected:
Number of children in each family | 0 | 1 | 2 | 3 | 4 or more |
Number of families | 6 | 184 | 672 | 127 | 11 |
Out of these families, a family was chosen at random. What is the probability that the chosen family has 2 children?
Total number of families: 1000
Number of families having no children: 6
Number of families having 1 child: 184
Number of families having 2 children: 672
Number of families having 3 children: 127
Number of families having 4 or more children: 11
Probability P() =
Let p(2) be probability of families having 2 children
P (2) =
P (2) = =
