given are:
250 adults and 180 parents
so we can solve the number of not parents
not parents = 250 - 180
not parents = 70
then we can number of people of votes for no
no not parents = 70 - 40  = 30
no parents = 180 - 150 = 30
             yes       no
parents     150        30
not parents  40         30
