Types of Problems

There is one type of problem in this exercise:

  1. Use picture, find probability: This problem has a diagram, chart or other visual aid drawn and asks for the probability of a particular event. The user is intended to types in the correct probability in the slot provided.

    Use picture, find probability


This exercise is easy to get accuracy badges because the visual aid is there for assistance. The speed badges are medium, due to time tolerances. Research was only able to get the very first basic one.

  1. Fractions do not need to be reduced.
  2. Use the picture. If users read the event carefully there is no good reason to get this one wrong unless you are misreading the problem.

Real-life Applications

  1. Probability, along with decimals, percents, and fractions are used to determine the probability of a basketball player making a shot.
  2. Data and statistics appear in news reports and in the media every day.
  3. Many of the problems in this exercise could be viewed as real-life applications.
  4. Statistics can be seen more frequently than calculus in every day life.
