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:
Substitute the values:
Final Answer:
The probability of rolling a number greater than 3 is:
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 outcomes/Total number of possible outcomes.
Substitute the values:
P = 3/6 = 1/2.
Final Answer:
The probability of rolling a number greater than 3 is:
1/2
