Answer 1

Answer:

⭐⭐⭐⭐⭐

(i) Number of families with 2 girls = 475

Total number of families = 150

P(E) =(Number of favourable outcomes)/(Total number of event)

=475/1500

=19/60

(ii) Number of families with 1 girl = 814

P(E) = (Number of favourable outcomes)/(Total number of event)

=814/1500

=407/750

(iii) Number of families with no girl = 211

P(E) = (Number of favourable outcomes)/(Total number of event)

=211/1500
