To find the probability of rolling a prime number or a number greater than 3, we first need to determine the prime numbers on a standard six-sided number cube. The prime numbers on a standard number cube are 2, 3, and 5.
Out of the possible outcomes (1, 2, 3, 4, 5, 6), the numbers that are prime or greater than 3 are 2, 3, 4, 5, and 6. So, the favorable outcomes are 2, 3, 4, 5, and 6.
The total possible outcomes when rolling a standard number cube are 6.
Therefore, the probability of rolling a prime number or a number greater than 3 is:
Number of favorable outcomes / Total number of outcomes
5 / 6
So, the answer is:
B. 5/6
