The prime numbers less than or equal to 6 are 2, 3, and 5. There are a total of 4 prime numbers or numbers greater than 3 on a standard, six-sided number cube: 2, 3, 4, 5, and 6. So, the probability of rolling a prime number or a number greater than 3 is 4/6 or 2/3.
Therefore, the correct answer is 2/3.
