At least one bear was sighted on 28 separate days in 40 day period total = 28/40
We're looking for the daily frequency of bear sightings, that's in the whole 40 day period.

Let's say 40 days period = 100%.
Then what's 28 days?

So the solution we're looking for would be (28 days∗100) / 40 days = 70%

The final answer is B. 70%.
