Asix-sided number cube is rolld twice, what is the probability that the first cough will be less than 4 and the second coughs withh be a number greater than 4?

Not sure what you mean by "cough". I assume you mean the number on the face.

The rolls are independent, so



For the first roll, there are three ways of getting a number less than 4 (1, 2, or 3) with a probability of .

For the second roll, there are two ways of getting a number greater than 4 (5 or 6) with a probability of .

So the probability of both events occurring in the prescribed order is .
