Introduction. The U.S. Constitution established Americaâs national government and fundamental laws, and guaranteed certain basic rights for its citizens. It was signed on September 17, 1787, by delegates to the Constitutional Convention in Philadelphia, presided over by George Washington. Under Americaâs first governing document, the Articles of Confederation, the national government was weak and states operated like independent countries.
Ictal refers to a physiologic state or event such as a seizure, stroke, or headache. The word originates from the Latin ictus, meaning a blow or a stroke. In electroencephalography (EEG) , the recording during a seizure is said to be ictal.
Mutually Exclusive Events. Two events are mutually exclusive if they cannot occur at the same time. Another word that means mutually exclusive is disjoint. If two events are disjoint, then the probability of them both occurring at the same time is 0. Disjoint: P(A and B) = 0. If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.
