Forty students from each 7th and 8th grade were asked which activity they prefer to do during the weekend. The results are shown below. How many students would you predict would choose the Zoo if 125 7th grade students were surveyed?

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.
