Question 1 Report

Find the probability of getting an even number in a single throw of a six-sided die.

Answer Details

A standard six-sided die has the numbers 1, 2, 3, 4, 5, and 6 on its faces. These are the possible outcomes when you throw the die—each one is equally likely.


First, let's figure out which numbers are even.
An even number is a number that is divisible by 2. Out of the numbers on the die (1, 2, 3, 4, 5, 6), the even ones are: 2, 4, and 6.


  • Even numbers: 2, 4, 6
  • Total even numbers: 3

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.


There are 3 ways to get an even number (2, 4, or 6), and there are 6 possible outcomes in total (1 to 6).


Using the formula:

\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]

\[ \text{Probability of getting an even number} = \frac{3}{6} \]


Now, let's simplify the fraction:

\[ \frac{3}{6} = \frac{1}{2} \]


Therefore, the probability of rolling an even number on a six-sided die is \\(\frac{1}{2}\\). This is because half the numbers on the die are even, and each outcome is equally likely.
