( i ). Total number of families, f = 1600
For no child, Probability = 55 / 1600 = 11 / 320
( ii ). For more than two children,
Probability = ( 470 + 360 + 165 ) / 1600 = 995/ 1600 = 199/ 320
For no child, Probability = 55 / 1600 = 11 / 320
( ii ). For more than two children,
Probability = ( 470 + 360 + 165 ) / 1600 = 995/ 1600 = 199/ 320
