There are 2 pieces of 6 sided dice we have. We roll them 5 times one after another. What is the probability that the numbers on the front side are same (same numbers) at least one times of 5 turns?
What I did so far is simplfy the question like what if we roll once:
1st dice could be any number(6/6)
2nd dice have to be same number with 1st dice(1/6)
Then result for the problem is (6/6).(1/6)=1/6
What if I roll them 5 times and I get same numbers at least one times? I guess each turn are independent from each other and I can't go for this way.
For this time, I thought that I have to look from different angle like what are the chances NOT to get same results and then substarct from 1. Could you help me about it?
