The problem is to find how many students have either blond hair or glasses and then divide that by the total number of students; that will find the probability.
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.

Answer: y = 1/3x +2
Step-by-step explanation:
The equation of line in slope - point form is given as:
y - 
= m ( x - 
)
m = 1/3
= 0
= -6
substituting into the formula , we have
y - 0 = 1/3 ( x - {-6} )
y = 1/3 (x+6)
y = 1/3x +2
