Question

paki · Answer

see... The sample space here is 1200... lets call n(a) = number of people with blue eyes hence n(a) = 252.. Therefore p(a) = n(a)/sample space which is 252/1200... solve which is 0.2...

subtract the ones you arent looking for and divide the remaining number by the total... from there you can solve for decimal percent or simplify the fraction.

252/1200 = 21/100 = 0.21 = 21%   @TaylorDyals
