Best ResponseYou've already chosen the best response.1The collective probability of any event cannot exceed 1. At least one of them selects a defected car means that there can be more than one defected cars picked. So, probability of at least 1 defective car = 1  (probability of no defective cars) For one person's pick, probability of nondefective car = 7/8. For five different draws, this will be (7/8)^5 Therefore, =>probability of at least 1 defective car = 1  ((7/8)^5) =>probability of at least 1 defective car = 1  (16807/32768) =>probability of at least 1 defective car = 1  0.5129 =>probability of at least 1 defective car = 0.4871

Best ResponseYou've already chosen the best response.0I thought it was somewhere along that line but i didnt subtract (7/8)^5 from 1. Thats why i didnt get it thank you again!!
