There are 4 contestants in a bicycle race. In how many different orders can they cross the finish line?

This is an Algebra 1 question. Easy 10 points!
There are 24 different orders in which the cyclists can finish the race. If we labeled each cycler as A, B, C and D, this can be seen manually:
ABCD
ABDC
ACBD
ACDB
ADBC
ADCB
BADC
BACD
BCAD
BCDA
BDAC
BDCA
CABD
CADB
CBAD
CBDA
CDAB
CDBA
DABC
DACB
DBAC
DBCA
DCAB
DCBA
If you have a scientific calculator though, it can be written as 4!. This means 4 x 3 x 2 x 1, and equals 24.
Similarly if you had 12 cyclists in this race, to work out the possible amount of finishing orders, calculate 12! and you will find there are 479,001,600 different ways!

Continental Race King MTB Bicycle Tire (26x2.0, Folding) List Price: $44.95 Sale Price: $26.38 |
|
Continental 0100128 Race King 26 x 2.0 Foldable MTB Tire is a talented newcomer as a cross-country speed merchant. The secret of the Race King is a large volume casing mated to a low-profile tread pattern that not only spells speed, but also incredible all-round traction and control. The continuous tread from crown to edge makes for fast, easy transitions from upright to ‘hard over’. Care must be taken about over cornering, though, because they don’t give you much feedback about how near to the edge of traction you are. The Kevlar bead is foldable. Specs: Weight - 480 grams; Recommended PSI - 50; Maximum PSI - 65; PU - 5. |
