Understanding the problem:
We are given that an unbiased die is thrown once. We need to find the probability of getting a prime number.
Prime numbers:
Prime numbers are the positive integers greater than 1 that have no positive integer divisors other than 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, and so on.
Calculating the probability:
To calculate the probability of getting a prime number when throwing an unbiased die, we need to determine the number of favorable outcomes and the total number of possible outcomes.
Possible outcomes:
When throwing an unbiased die, the possible outcomes are the numbers from 1 to 6. So, there are 6 possible outcomes.
Favorable outcomes:
To determine the favorable outcomes, we need to identify the prime numbers from 1 to 6. The prime numbers in this range are 2, 3, and 5. So, there are 3 favorable outcomes.
Probability calculation:
The probability of an event occurring is given by the formula:
Probability = Number of favorable outcomes / Total number of outcomes
In this case, the probability of getting a prime number is:
Probability = 3 (favorable outcomes) / 6 (total outcomes) = 1/2
Therefore, the correct answer is option 'C' (1/2).
