In a survey of 100 families having 2 or less boys. The following data was obtained:


Number of boys in a family



0



1



2



Number of families



18



46



36



If one of the given families is chosen at random, what is the probability that the chosen family has


(i) 1 boy? (ii) 2 boys? (iii) no boy?

Total number families surveyed = 100


Number of families having no boys = 18


Number of families having one boy = 46


Number of families having two boys = 36


Probability P() =


(i) Probability of family having one boy


P(one boy) =


(ii) Probability of family having 2 boys


P(two boy) =


(iii) Probability of family having no boy


P(no boy) =


16
