Propane tanks can be filled at the Sunshine Gas Company for $7.50 per tank if customers pay a one time membership fee of
$10. Which formula best describes the total cost C in dollars
of filling T propane tanks at the member price (including the
membership fee)?
A А
C = 11T + 7.50
с
C = 7.50T + 10
B
C = 17.50T
D
C = 10(7.50 +T)

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.
