Problema Solution
biologists banded 2 out of every twenty wild ducks. what percentage were not banded?
Answer provided by our tutors
2 were banded thus 20 - 2 = 18 were not banded
the percentage of not banded ducks = the ducks that were not banded/total number of ducks
the percentage of not banded ducks = 18/20
the percentage of not banded ducks = 0.9 or 90% of the ducks were not banded.
