25-35 years old	5%	20%	12%

>55 years old	3%	5%	5%

8) P (Age between 25-55 OR income more than $50,000)

9) P (Age between 25-55 AND income more than $50,000)

10) P (Income less than $25,000 and age between 25-55 years old)

11) P (Age under 55 years and income less than $50,000)

Answer 1

8)

Required probability = P(Age between 25-55 or income more than $50,000)

= P(Age between 25-55) + P(income more than $50,000) - P(Age between 25-55 and income more than $50,000)

9)

Required probability = P(Age between 25-55 AND income more than $50,000)

10)

Required probability = P(income less than $25,000 and age between 25-55 years old)

11)

Required probability = P(Age under 55 years and income less than $50,000)
