Mutually exclusive events

What's the probability that an employee in Italy belongs to the age group "From 15 to 24" or "From 25 to 54"?

P(15 to 24 years or 25 to 54 years) = P(15 to 24 years) + P(25 to 54 years)

Non-mutually exclusive events

What's the probability that an adult employee is either "From 15 to 24 years" or "Male" in Italy?

P(15 to 24 years or Male) = P(15 to 24 years) + P(Male) − P(15 to 24 years and Male)

Conditional probability

What's the probability of an employee in Italy being male given that the person is in the "From 15 to 24 years" age group?

P(Males|15 to 24 years) = P(Male and 15 to 24 years) / P(15 to 24 years)

Bayes' Theorem

What's the probability that a randomly selected employed person in Italy is between 15 and 24 years old, given that they are male?

P(15 to 24 years|Males) = P(15 to 24 years) * P(Males|15 to 24 years) / P(Males)
