Note: I have already answered this question.
Given that total number of cards n(S) = 113.
(1) Let A be the favorable outcomes of getting a square number.
Square numbers from 11 to 123 = 16,25,36,49,64,81,100,121.
n(A) = 8.
Therefore the required probability P(A) = n(A)/n(s)
= 8/113.
(2) Let B be the favorable outcomes of getting a number multiple of 7.
Multiple of 7 between 11 to 123 = 14,21,28,35,42,49,56,63,70,77,84,91,98,105,112,119.
n(B) = 16.
The required probability P(B) = n(B)/n(S)
= 16/113.
Hope this helps!
