we can discard the random part good values are 56-42 which are at a range of 7 from 49. so total pòssible sqares
56-42+1 = 15 (taken from the fromula to know how many numbers are from x to y) 15/100 equals 15%
56-42+1 = 15 (taken from the fromula to know how many numbers are from x to y) 15/100 equals 15%
