Answer 15

right?

Answer 16

@Shubhamsrg

Answer 17

nos divisible by 2= 100,102...998 ->450 nos.

nos divisible by 6(both 2 and 3) = 102,108..996 ->150 nos.

so total nos we have to take care of = 450 - 150 = 300

total nos. from 100 to 999 = 900

so our required probability = 300/900 = 1/3
as @sauravshakya rightly said.
