<span>A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches
Now let’s find the length that is between the span of the two given length:

fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10
Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5
Therefore the number we are looking 0.4

Options B and C are unbiased as here a selection of each number and name of the student has an equal chance of being selected.
Option D is biased because Sergio talked adults at a local fitness center where people go for maintaining their health. So, there is a chance of the selection of fitted adults more than unfitted adults.
Option E is biased because Josh met people at the dog park where dog lovers are more than a cat lover.
