~~~~~~~~~~~~~~~ 

There are 90 (ninety) two-digit numbers: they are from 10 to 99, inclusive.


Of them, there are 5 two-digit numbers divisible by 19: they are 19, 38, 57, 76, 95.


Therefore, the probability to choose randomly a two-digit number multiple of 19 is  5%2F90 = 1%2F18.    ANSWER


Find an appropriate option in your list.
