8 0

Answer:

1680 ways

Step-by-step explanation:

8P4=8!/(8-4)!

=8!/4!

=8×7×6×5

Step-by-step explanation:

The reason why polls are carried out is to obtain information that can represent the opinions, status or habits of the population. The polls do not include the total population, then include a small number of participants, but the results are extrapolated to the general population.
