Two numbers are selected without replacement at random, one at a time from the first six positive integers. Let x denotes the larger of the two numbers. Match List-I with List-II
Choose the correct answer from the options given below: |
(A)-(II), (B)-(III), (C)-(IV), (D)-(I) (A)-(III), (B)-(IV), (C)-(I), (D)-(II) (A)-(IV), (B)-(I), (C)-(II), (D)-(III) (A)-(I), (B)-(II), (C)-(III), (D)-(IV) |
(A)-(II), (B)-(III), (C)-(IV), (D)-(I) |
The correct answer is Option (1) → (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
The first six positive integers are: 1, 2, 3, 4, 5, 6. Total number of ways to choose 2 numbers (without replacement): 6C2 = 15 Let $x$ denote the larger of the two selected numbers. (A) $P(x = 2)$: Only one pair possible: (1,2) → larger = 2 So, $P(x=2) = \frac{1}{15}$ (B) $P(x = 3)$: Valid pairs: (1,3), (2,3) → 2 pairs $P(x=3) = \frac{2}{15}$ (C) $P(x = 4)$: Valid pairs: (1,4), (2,4), (3,4) → 3 pairs $P(x=4) = \frac{3}{15} = \frac{1}{5}$ (D) $P(x = 5)$: Valid pairs: (1,5), (2,5), (3,5), (4,5) → 4 pairs $P(x=5) = \frac{4}{15}$ |
