Explorática 2.0 is an initiative of the National Institute of Statistics, aiming to bring to the educational communities the foundations of Statistics and Probabilities (with a special focus on Sampling), transmitting the concepts in a practical and experimental way.

Explorística 2.0 integrates several games, each involving various activities such as selecting, collecting, describing and estimating.

Dr. Odd - Dr. Odd was murdered in his mansion. Five weapons, which must be discovered, may have been used in this crime; On the other hand, there are six suspected murderers. Knowing the probabilities that each weapon is the weapon of crime and that each suspect has used each weapon, players must calculate which suspect is most likely to be the criminal.

This game aims to explain the use of conditional probabilities and the usefulness of the Venn Diagram in this context.
