To determine the probability of rolling a number greater than 3 on a standard number cube (die), we will follow these steps:
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.
The numbers greater than 3 on a standard cube are: 4, 5, and 6.
So, there are 3 favorable outcomes.
A standard cube has 6 faces, so there are 6 possible outcomes in total.
The probability P of an event is given by:
Substitute the values:
The probability of rolling a number greater than 3 is:
Step 1:
Understand the ProblemA 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 OutcomesThe numbers greater than 3 on a standard cube are: 4, 5, and 6.
So, there are 3 favorable outcomes.
Step 3:
Identify Total Possible OutcomesA standard cube has 6 faces, so there are 6 possible outcomes in total.
Step 4:
Calculate the ProbabilityThe 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
