I realize this was answered 2 years ago, but for anyone searching for this problem, the Best Answer is not correct since it assumes the independence of events A and B. Notice that P(A and B) is given to be 0.88, but P(A)P(B) 0.855, hence A and B are not independent. A better approach is to use the additive law: P(smoke is detected by either device)P(A U B)P(A) + P(B) - P(A and B)0.95 + 0.90 - 0.880.97 The second part of the problem is 1 - 0.97 0.03.
For tires good for 3 seasons (not winter), the Goodyear Eagle F1 GS-D3 and Goodyear Eagle F1 Asymmetric have tested well for wet weather, possibly the best. If you want good ice and snow capability and also wet road tires, consider Nokian Hakkapeliitta R with Michelin X-Ice Xi2 being a 2nd choice and Bridgestone Blizzak WS60 as a third. Xi2 have the best ice and snow among non-studded tires but are 3rd among these 3 for wet. If you are looking at all seasons, note that all seasons are inferior in the winter. Even BMW's owner's manual says so. With that in mind, you have mentioned what is probably the best among the all seasons, Pilot Sport A/S Plus and RE960AS. The Dunlop SP Sport Signature is very good and much cheaper but not as good as the other two. The Goodyear Eagle F1 All Season is a noisy tire, according to many people. One disclaimer, Continental makes many tires but I have not kept up with their line. They have some new models. They do make some good tires, both by others' reports and my experience in the late 90's. Also be careful when driving in the wet. Your traction is much less than dry. Tires help a whole lot but do have limitations.
