Set S of cardinality 7 has distinct elements. Is the probability of picking out a prime number
from Set S less than 4/5?
(1)The least element and the largest element of Set S are 8 and 18 respectively.
(2)If two prime elements are added into Set S, the probability that a prime number is picked
up from the extended set S is 1/3
(A)Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
(B)Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer tlVe question asked.
(C)BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient.
(D)EACH statement ALONE is sufficient to answer the question asked.
(E)Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
