Q2. 1500 families with 2 children were selected randomly, and the following data were recorded:
Compute the probability of a family, chosen at random, having
(i) 2 girls
From the above question, the data that we can take is,
Total Number of families= 475+814+211 = 1500
Number of families having 2 girls in the family =475
We know:
Empirical (or experimental) probability P(E) of this event can be written as
P(Family, chosen at random has 2 girls) =
= 475/1500 = 19/60
