Answer 2

answer is option a.) 0

this is because, the first no. of the set is 11.

hence, the probability will be found of a two digit no.

but, in the question, it is asked to find the probability of 9 which is a single digit no. and is totally impossible to occur.

and we know that the probability of an impossible event is 0.
