Answer 1

Answer:

P(owns 2 cars annual income is greater than 8 lakhs ) = 0.75

P(annual income is greater than 8 lakhs) = 0.60

P(2 cars) = 0.52

P(owns 2 cars and annual income is greater than 8 lakhs) = 0.75 x 0.60 = 0.45

Explanation:

P(owns 2 cars annual income is greater than 8 lakhs ) = 0.75

P(annual income is greater than 8 lakhs) = 0.60

P(2 cars) = 0.52

P(owns 2 cars and annual income is greater than 8 lakhs) = 0.75 x 0.60 = 0.45
