From that, we can see in the Venn diagram that the tiger must also be inside the set of mammals, so the conclusion is valid. Cats are a subset of creatures that are scared by vacuum cleaners. Max is in the set of cats, so he must also be in the set of creatures that are scared by vacuum cleaners. From the first premise, we know that firefighters all lie inside the set of those who know CPR. Firefighters are a subset of people who know CPR. From the second premise, we know that Jill is a member of that larger set, but we do not have enough information to know whether she also is a member of the smaller subset that is firefighters.
Since the conclusion does not necessarily follow from the premises, this is an invalid argument. It is important to note that whether or not Jill is actually a firefighter is not important in evaluating the validity of the argument; we are concerned with whether the premises are enough to prove the conclusion.
The set of bicycles is a subset of the set of vehicles with two wheels; the Harley-Davidson is in the set of two-wheeled vehicles but not necessarily in the smaller circle. Since no cows are purple, we know there is no overlap between the set of cows and the set of purple things.
We know Fido is not in the cow set, but that is not enough to conclude that Fido is in the purple things set. From the first premise, we know that the set of people who live in Seattle is inside the set of those who live in Washington.
From the second premise, we know that Marcus does not lie in the Seattle set, but we have insufficient information to know whether Marcus lives in Washington or not.
