Quick question from probabilities

The following table summarizes the availability of trucks with air bags and bucket seats at a dealership. Bucket seats No Bucket Seats Total Air Bags 75 50 125 No Air Bags 35 60 95 Total 110 110 220 What is the probability of randomly selecting a truck with air bags and bucket seats? A) 0.28. B) 0.16. C) 0.34. Your answer: A was incorrect. The correct answer was C) 0.34. 75 ÷ 220 = 0.34. I chose A, because I thought abt multiplying P(AirBags)*P(bucket seats)= 56,8%*50%. Why isn’t that correct? Thanks, T.
