Show answer & explanation
Correct answer: B
Correct Option
Option B: 1/2
Step-by-Step Solution
Identify the Sample Space:
A standard six-sided die has the following possible outcomes: {1, 2, 3, 4, 5, 6}.
Total number of possible outcomes = 6.
Identify Favourable Outcomes:
The even numbers within the sample space are {2, 4, 6}.
Total number of favourable outcomes = 3.
Calculate Probability:
Probability = Favourable Outcomes / Total Outcomes.
Probability = 3 / 6.
Simplified, this equals 1/2.
