Compute the probability of a family chosen at random having
(i) 2 girls. (ii) No girl.

∴ Total number of families = 1500 [given]
(i) Since, the number of families having 2 girls in a family = 475
∴ P (having 2 girls) = 475/1500 = 19/60 = 0.32
(ii)Since, the number of families having no girl in a family = 211
∴ P( having no girl)=211/1500=0.14
