Hi
  The National Association for Women in Science asked recent high school grads
 if they had taken certain science classes. Of those surveyed, 90 said they had
 taken physics, 138 said they had taken chemistry and 45 said they had taken
 both. Thirty-two said they had taken neither.
 Only Physics   = 90 - 45 =  45
 Only chemistry = 138 - 45 = 93
                   Neither = 32     | 170 recent high school grads were surveyed
