Out of 25 students 9 of them are wearing blue. The probability of a student who is not wearing blue is 16/25.
Convert 13/25 into a percentage. Divide 13 by 25 and you get 0.52, which is 52%.
That is greater than 50%, so 13/25 is greater than 50%
Percent is parts out of 100 so x%=x/100 so
93%=93/100
