To determine the probability of rolling a number greater than 3 on a standard number cube (die), we will follow these steps:

Step 1:

Understand the Problem
A standard number cube has 6 faces, numbered from 1 to 6. We want to find the probability of rolling a number greater than 3.

Step 2:

Identify Favorable Outcomes
The numbers greater than 3 on a standard cube are: 4, 5, and 6.  
So, there are 3 favorable outcomes.

Step 3:

Identify Total Possible Outcomes
A standard cube has 6 faces, so there are 6 possible outcomes in total.

Step 4:

Calculate the Probability
The probability P of an event is given by:

P = Number of favorable outcomesTotal number of possible outcomes.


Substitute the values:

P = 36 = 12.

Final Answer:


The probability of rolling a number greater than 3 is:

12
