There are x hats on a hat rack. If one hat were to be selected at random, the probability that the hat would be green is 2/5 . The probability that the hat would be black is 1/5 . If the only other color remaining is red, what is the total number of red hats in terms of x?

no of green hat       2
------------- = --
         x                    5
no of green hat = 2x/5

no of black hat       1
------------- = --
         x                    5
no of black hat = x/5
no of red hat= total no of hats - no of black hats - no of green hats
                     = x - x/5 - 2x/5
                     = (5x - x-2x ) /5
                     = 2x/5
