The probability of the first event with x possible outcomes is equal to x/30. Also, the probability of the second event with y possible outcomes is y/29.
(1) P of 2 digit number, 21/30
P that the number is 4 is 1/29
Multiplying both probabilities will give us 7/290
(2) P that number is 19 is 1/30
P that the number is multiple by 4 is 6/29
The answer is 1/145
(3) P that number is 24 is 1/30
P that number is less than 15 is 14/29
The answer should be 7/435.
(4) P that number 1st number is perfect square is 5/30
P that second number is perfect square is 4/29.
The answer is 2/87.
