two numbers b/w 1 and 30 inclusive are drawn in a contest. what is the probability that both numbers are eve?

they have (15/30)15/30

i thought i should be (15/30)(14/29)

but the answer is (15/30)(15/30)= 1/4

how come? (

**does this mean that they put the first number back in and then drawn for the second time?)**
