So here we have, except that it doesn't have to be a probability distribution, so for example, if we have a factor here who's scope is A, B, and C. And we want to marginalize out B, to get a factor whose scope is A, C: what we're going to be doing is, again, taking both possible values of B, in this case there's on - because B is binary there's only two values, and we add them up, in order to get the entry for a1, c1: so 0. 25 plus 0. 08.

Así por ejemplo, si tenemos un factor aquí cuyo alcance es A, B y C, y queremos marginalizar B, para obtener un factor cuyo alcance es A, C, lo que vamos a estar haciendo es, nuevamente, tomar los posibles valores de B, en este caso hay solo dos porque B es binario, y los sumamos, a fin de obtener la entrada para a1, c1: 0, 25 más 0, 08.
