B)
(i) (ii) (iii) (iv) 1/19 1/19 8/19 9/19
C)
(i) (ii) (iii) (iv) 8/19 8/19 16/19 9/19
D)
(i) (ii) (iii) (iv) 8/19 8/19 17/19 9/19
Correct Answer: C
Solution :
Total number of possible outcomes =19 (i) Prime numbers are 2, 3, 5, 7, 11, 13, 17, 19. \[\therefore \] Probability of numbers being prime = 8/19 (ii) Numbers divisible by 3 or 5 are 3, 5, 6, 9, 10, 12, 15,18. \[\therefore \] Required probability = 8/19 (iii) Numbers neither divisible by 5 nor by 10 are 1,2, 3,4, 6, 7, 8, 9, 11, 12, 13, 14, 16, 17, 18, 19. \[\therefore \] Required probability =16/19 (iv) Even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18. \[\therefore \] Required probability =9/19
