You can put this solution on YOUR website! Sample space,S={10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30}
n(S)= 21.
Let A be the event of taking multiple of 4.
A = {12,16,20,24,28}
n(A) = 5.
Probability of A = number of favourable chance / Total chance.
P(A)= n(A)/ n(S).
= 5 / 21.
The probability of selecting multiple of 4 is 5/21.
