In a certain population suppose 4% of boys are color blind and 1.4% of girls are color blind. we do a color blind test to a sample of children from this population, 60% of whom are boys. what percentage of the color blind children do we expect to be girls? let: b = child is a boy b' = child is not a boy (i. e., is a girl) c = child is color blind c' = child is not color blind

0.56 % of the total population

Explanation:

If in a certain population we know that the 60 % represent the boys and the 40 % represent the girls.

So the 40 % of girls is the 100 % of all the girl sample and just 1.4 % of girls are color blind. So..

40 % = 100 %

x        =  1.4 %

x= (1.4 %  x 40 %) / 100 %  = 0.56 % of the total population.

Hope this info is useful
