Всього беруть 10 коней участь у перегонах. Тобто один кінь не може мати по декілька призових місць. Отже, перше місце може мати один з 10 коней, друге - один з 9, і третє відповідно - один з 8.

N=10*9*8=720 способів.

What do you do when you wake up and you
don't feel well? You've got a sore throat and
a headache. You feel sick and you can't go
to school. Well, you don't always have to go
to the doctor for help. First, you should visit
your local chemist. You can go to them and
ask for advice. Chemists will listen to you and
suggest what pain killers or medicine you
if you should
snould take. They can tell you
stay at home or if you should see a doctor.
They sell all kinds of painkillers and medicine
so they should have something that you
need.
Chemists don't only sell medicines. They also
sell products such as shampoo. soap and
perfume. They sometimes have a notice
board on the wall where you can read notices
about local exercise classes and clubs. We
all know that we should eat healthy food and
that we should exercise regularly, but we
don't always do it!
Most chemists are open from Monday to
Saturday from nine in the morning until 5.30
in the afternoon. They sometimes close for
lunch from cne until two, and in small towns
they often close for one afternoon a week.
But there's always a chemist open in your
area. Phone 098 558723 to find out which
chemist in your area is open in the evening
and on Sunday. Or you can look at the list in
your chemist's shop window.
Chemists are qualified professionals. They
can give you professional advice and save
you a trip to the doctor, However, they aren't
doctors and if a baby is ill, or you have a
serious health problem, you must call your
doctor immediately.
