Step-by-step explanation:
here,
total outcomes= 1500
no.of families with no girl= 723
therefore, P(0)= 723/1500 = 241/500
the probability of families with only one girl ( if the question doesn't mention at least one girl it'll be on the same format)
P(1)= 675/1500 = 135/300=27/60=9/20
probability of one girl P(1) = 102+675/1500
= 777/1500
