Answer 1

(I) The probability of bringing out a square number will be 1/6.

(ii) The probability of getting the prime number will be 11/36

(iii) The probability of getting a number divisible by 3 will be 1/3

The formula for the probable outcome of the event is P(outcome) = Number of outcomes / Total number of outcome.

Answer 2

The probability of drawing a non-perfect square number from the cards numbered 1 to 30= 5/6
