we are looking for the # of boys lEFT-HANDED
Now, 60% of 45 in total we do have 27 boys
45-27=18 girls
So we do have 27 boys and 18 girls. We do not care about the # of girls therefore the boys left -handed are 27-18=9
The total # of boys left-handed are between 9 and 27.
regardless B is 8. But our minimum number we are looking for is 9
A > B
