and Mr. Harold are blessed with many children. Things are especially
fun at dinnertime.
Seven children like
to eat cabbage, six kids like carrots, and five enjoy peas.
Four kids like both cabbage and carrots, three kids like cabbage
and peas, and two of them like carrots and peas.
And one kid does not fuss, but loves all three vegetables: cabbage,
carrots, and peas.
How many children do
Mrs. and Mr. Harold have?
