Question 1077104: hi everyone,
i have a quick question,
A large company that must hire a new president prepares a final list of five candidates,
all of whom are equally qualified. Two of these candidates are members of a minority group.
To avoid bias in the selection of the candidate, the company decides to select the president
by lottery.
the probability one of the minority candidates is hired we just need to divide the number of favorable outcomes 2 by the number of possibilities 5 and then we will have 0.4 but my questions is
Which concept of probability did you use to make this estimate?
thank you

5 candidates.
2 are members of a minority group.
the probability that the person selected is a minority is 2/5 = .4

the concept is that the probability of picking a candidate who is a minority is 2 out of 5 because there are 2 minority candidates out of a total of 5 candidates.
the probability of an occurrence is the number of ways you can get that occurrence devided by the number of ways you can get all occurrences.

here's simple definition from the web:
