Answer
c.
The problem does not tell you the probability that a random box contains an olive pizza. However, the problem
does tell you the probabilities of a box containing the other types of pizza. If you add together all those proba-
bilities, you will know the probability that a box contains a pepperoni, a mushroom, an onion, or a sausage
pizza. In other words, you will know the probability that a box does NOT contain an olive pizza:
pepperoni 
mushroom 
onion 
sausage

Practice Test 1
This practice test is a simulation of the three Math sections you will
complete on the SAT. To receive the most benefit from this practice test,
complete it as if it were the real SAT. So, take this practice test under
test-like conditions: Isolate yourself somewhere you will not be dis-
turbed; use a stopwatch; follow the directions; and give yourself only
the amount of time allotted for each section.
