A) \[\frac{11}{90}\]
B) \[\frac{33}{90}\]
C) \[\frac{55}{90}\]
D) \[\frac{164}{191}\]
Correct Answer: D
Solution :
(d): The number of favourable events will be given by 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140,.........196. Thus, the number of all 2 ? digit integers divisible by 7 is 9 + 10 + 8 = 27 \[\therefore \]\[P=\frac{191-27}{191}\] (as total no of 2 digit integers =191)
