please solve the query soon . Thank you .

If a pair of dice is thrown twice, what are the possible outcomes?

I think it'll be 6

^{4}=1296 as when two dice are are thrown simultaneously, the number of outcomes are equal to a dice thrown twice, i.e. 6^{2}=36.Hence if we throw a pair of dice two times, the outcomes would be equal to throwing 4 dice simultaneously or throwing a dice 4 times, i.e., 6

^{4}=1296.Am I correct? If not plz explain........

Then there are ques....

If a pair of dice is thrown twice, what is the probability of getting

(i) 2 as the sum of numbers (I think 1/1296)

(ii) a doublet (I think 1/36)

(iii) 8 as the sum of numbers

Someone explain please........
