so, x+y = 11
now ,the prime no. of 2 digit ,, the sum of whose Digits is 11
83 = 8+3 = 11
47 = 4+7 = 11
29 = 2+9 = 11

(ii) 1/2

Step-by-step explanation:

Hope the question meant: sum of digits of a two digit number is '11'

The numbers can be

29 , 92 , 38 , 83 , 47 , 74 , 56 , 65

Total outcomes = 8

(i) prime number: 29,83,47

Probability = No. of favorable outcomes/Total outcomes = 3/8

(ii) either divisible by 2 or 3: 92,38,74,56

Probability = 4/8 = 1/2
