A school hosted a football game last week. Ticket sales totaled $649 between student and adult tickets sold. Student tickets cost $2 each and adult tickets were $5 each. There were a total of 167 people in attendance. Figure out how many of each type of ticket were sold.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
