A probability experiment is conducted in which the sample space of the experiment is sequalsstartset 1 comma 2 comma 3 comma 4 comma 5 comma 6 comma 7 comma 8 comma 9 comma 10 comma 11 comma 12 endset?, event upper f equals startset 4 comma 5 comma 6 comma 7 comma 8 comma 9 endset?, and event upper g equals startset 8 comma 9 comma 10 comma 11 endset. assume that each outcome is equally likely. list the outcomes in f or g. find upper p left parenthesis upper f or upper g right parenthesis by counting the number of outcomes in f or g. determine upper p left parenthesis upper f or upper g right parenthesis using the general addition rule.'
