TV TEASE
Mr Hearty wants to watch four TV programmes, all on
between 7pm and 9pm. One of the programmes lasts
an hour, another lasts 40 minutes and the other two
each last half an hour.
Without knowing the exact times of any of the
programmes, what is the least number of minutes of
the programmes, in total, that Mr Hearty will have to
miss? He doesn't own a video recorder
APRIL SOLUTION
THE HAIRY SITUATION
Uncle Jack knew that the number of hairs on a hu-
man head is at most about 200 000 while the total
population of the world is more than 5 000 000 000.
Therefore, on average, you can expect about 25 000
other people to have the same number of hairs on their
heads as on yours. The chance that no-one has the
same number is so small as to be insignificant, which is
why Uncle jack was smiling to himself, even though he
had never counted the hairs on Gary's head.
