The table gives the probabilities that new cars of different models will have brake failure. The car model that is least likely to have a brake failure is model, and the probability of brake failure for this model is %.

Car Model Brake Failure

in New Car

A 0.0065%

B 0.0037%

C 0.0108%

D 0.0029%

E 0.0145%

Total 0.0048%

All the information we have are the probabilities, and what we need is the lowest number: so let's choose the smallest probability among the numbers: 0.0065%, B 0.0037%, C 0.0108%, D 0.0029%, E 0.0145%. The smallest of the numbers is 0.0029% - it starts with two 00s and the number that follows, 2, is smaller than all there others - so the smallest probability is in option D - and the model would be the corresponding model (but we're missing some information here)
