The following data sufficiency problems consist of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are
sufficient
for answering the question. Using the data given in the statements
plus
your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient. [br] The hold of a fishing boat contains only cod, haddock, and halibut. If a fish is selected at random from the hold, what is the probability that it will be a halibut or a haddock?
(1)There are twice as many halibut as cod in the hold, and twice as many haddock as halibut.
(2) Cod account for 1/7 of the fish by number in the hold.
选项
答案
D
解析
alone is sufficient because it means that if there is one cod, there are two halibut and four haddock, so halibut and haddock account for 6/7 of the fish in the hold, giving a probability of 6/7 of selecting one of these fish. (2) alone is sufficient, because the probability of selecting a cod is the inverse of the probability of selecting one of the other two fish, or 6/7.
