I'm not sure if I'm correct though. The probability that the first cube lands showing a 1 and the second cube lands showing a number that is not 1 is (0.139)

the probability the first cube lands on a one is 1/6
probability second cube does not land on a one is 5/6
now multiply these probabilities since you want the conjunction of the events
