The probability that the car will need repair ; p(need repair) = 0.4
The probability that the car will not need repair ; p(no repair) = 1 - 0.4 = 0.6
Probability at least 1 will need repair = 1 - Probability none will need repair
Probability at least 1 will need repair = 1 - p(no repair)
=
The probability that at least one of them will require repairs in the first six months is 0.972
