Two dice are tossed, one after the other. What is the probability that the result is a sum of 6, given that the first toss is not a 3? (Enter your probability as a fraction.)

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
