This section contains 6 questions. Questions 83 to 88 have four statements (A, B C and D) given in Column I and four statements (p, q, r and s) in Column II. Any given statement in Column I can have correct matching with one or more statement(s) given in Column II. 83. Column I (A) If P(A) = 0.3, P(B) = 0.4 and P(AB) = 0.5 and P[B/(AUB)]=2, then- is (B) The coefficient of a quadratic equation ax + bx+c=10(a + b + c) are chosen from first three prime numbers, then the probability that roots of the equation are real is 2, then is 2 (C) A fair coin is tossed repeatedly. If tail appears on first four tosses, then the probability of head appearing on the fifth toss is 23, then is 3 (D) Three persons A, B and C are to speak at a function along with 6 other persons. If the persons speak in random order, then the probability that A speaks before 1 B and B speaks before C is A4, then- is 2 Column II (p) A prime number (q) A composite number (r) A natural number (s) A perfect number This section contains 6 questions.
