Apen costs twice as much as a pencil. the total cost of 1 pen and 1 pencil is $2.10. if p represents the cost of 1 pencil, which equation could you use to find p a. 2p+p=10 b. p/3=2.10 c. 2p=2.10 d. p+p=2.10

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.
