    2. The Disaster

    3. God Does Not Play Dice… Using Data Mining, we can predict an individual’s survival by asking only three questions: Is the person male or female? Is the person an adult or a child? Is the person a crewmember, or a 1st class, 2nd class, or 3rd class passenger? By asking these three questions, we can accurately predict the individual’s survival over 75% of the time.
