A spinner has four regions , , , . On any spin it lands on
What is the Shannon entropy of a single spin, in bits?
Once you get it right, the reasoning behind the answer shows up here.
Select all that apply.
Entropy measures average uncertainty. A coin flip has max uncertainty ($H = 1.0$ bit) when fair ($p = 0.5$), and zero uncertainty ($H = 0$ bits) when fully biased ($p=0$ or $1$).
