A Relay
it is a baton
A relay race.
4 runners & a baton.
A baton is the object that is passed between relay runners in a relay race.
To form a 4-person relay team from 8 track runners, we first choose 4 runners from the 8, which can be done in ( \binom{8}{4} = 70 ) ways. Then, we can arrange these 4 runners in ( 4! = 24 ) different ways. Therefore, the total number of arrangements is ( 70 \times 24 = 1680 ). Thus, there are 1,680 ways to arrange 8 track runners on a 4-person relay team.
If you're thinking of the short wooden or metal 'stick' they pass between the runners - that's called a baton.
1949 and in the backstroke relay!!
fingure it out, sorry
Typically a team of 4 runners. They'll probably have some backup runners ready in case one or more runners fall ill at an inconvenient moment.
