If a pair of dice is thrown twice, what are the possible outcomes?
I think it'll be 64=1296 as when two dice are are thrown simultaneously, the number of outcomes are equal to a dice thrown twice, i.e. 62=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., 64=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
