The probability of the two independent events occurring together is $latexp_{1}p_{2}$, so the associated measure of information is. Zach Wissner-Gross leads development of math curriculum at Amplify Education and is FiveThirtyEights Riddler editor. Every single guess you make should be a possible winner, according to the information you have at a given time.

Combining the knowledge from the different hints means adding information together, which gets us closer to our goal of four bits. Source-code cheating aside, the computational challenge still stands - how would you pick words so that you maximize your chances of winning the game? When two events are independent, and thus dont influence each other, knowing about one doesnt give you any information about the other, so it makes sense to add up information in this situation.

A digital photo of a polar bear in a snowstorm wouldnt contain much information because all the pixels would be predictably white. First, the sum of a probability times something is an expectation, so the entropy is the expected value of the negative log probability of the outcome: Whats the negative log probability of the outcome? Apparently not. You also have a 2/7 chance of (AS, AT), and a 1/7 chance of (AB). The less predictable something is, the more information it contains. Lets start by taking a look at the words in our possible answer set, and identify the letters in each position. View the possible words list.
