Question

​

Answer 1

Answer:

If in an Oregon state gubernatorial election, 2 of the 5 candidates are women, and a statistics student establishes that there is a 2/5 chance that the person elected for governor is a woman, this reasoning will be wrong.

This will be the case because not all candidates have the same amount of votes, that is, not all start with the same conditions: thus, there are more popular candidates than others, who will have greater probabilities of being elected as governors, regardless of their sexual identity.
