Note that the complement of an event in probability is essentially the same as the complement of a set, since an event is a subset of the sample space. It is possible for a card to be both red and a 5 at the same time but it is not possible for a card to be both red and a spade at the same time.
However, the outcomes are not equally likely since you can get one head by getting a head on the first flip and a tail on the second or a tail on the first flip and a head on the second.
