Afish tank has a base area of four 45cm2 and it is filled with water to a depth of 12 cm. if the height of the tank is 25 cm, how much more water will be needed to fill the tank to the brim?

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.
