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) =
