Given the frequency table on the relationship between red hair and green eyes.
   Green Eyes Eye Color other than Green    Total
Red Hair 18    29 47

Hair Color
other than    114    650 764
Red

Total    132    679    811

The relative frequency table is obtained from a frequency table by dividing each entry of the requency table by the overall total of the frequency table.

The relative frequency table of the frequency table above is given below.
   Green Eyes     Other Eye Color     Total
Red Hair   18/811 = 0.02 = 2% 29/811 = 0.04 = 4% 47/811 = 0.06 = 6%

Other Hair
Color    114/811 = 0.14 = 14%|650/811 = 0.80 = 80%|764/811 = 0.94 = 94%

Total 132/811 = 0.16 = 16%|679/811 = 0.84 = 84%|811/811 = 1.0 = 100%

Given that x is the relative frequency of people that have other hair color and have green eyes, thus, the value of x is 14%.

Therefore, <span>the value of x in the table = 14%.</span>
