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
(iii) No girl
From the above question, the data that we can take is,
Total Number of families= 475+814+211 = 1500
Number of families having no girls in the family =211
We know:
Empirical (or experimental) probability P(E) of this event can be written as
P(Family, chosen at random has no girls) =
= 211/1500
Ans:= 211/1500
