12. Entropy Formula 3

Entropy Formula

Corrections:

  • At 0:15, the fourth log should be log(0.25) instead of log(0.75). The final sum, -3.245, is still correct for log(0.75) + log(0.75) + log(0.75) + log(0.25), using a base of 2.
  • At 0:29, the value in the first row for P(Blue) should be 0, not 1.
  • At 1:22, the formula has a denominator of m-n. It should be m+n.
