children in a running race on Sports Day. The children’s names are
Aaron, Katie, Sunita and Gary.
If they all finish the race how many possible orders are there of
the children crossing the finishing line?
|
|
| How many ways
of finishing would there be if there were 5,6 and 7 people in
the race. Can you
predict how many there would be for 8 children? |
|
How
many ways are there of girls winning the race?
What do you notice about the number of girls winning the
race? |
|
|
|
| If the number
of girls increased to 3 how would this affect the number of
possible ways that the girls could win the race? |
|
Can you find
a formula that would let you work out the number of ways of
finishing for any number of athletes? |
