a number cube numbered 1 through 6 is rolled.what is the probabilty of rolling a prime number.
To find the probability of rolling a prime number on a number cube numbered 1 through 6, we need to determine the number of favorable outcomes (prime numbers) and the total number of possible outcomes.
The prime numbers between 1 and 6 are: 2, 3, and 5. So, there are 3 favorable outcomes.
The total number of possible outcomes is 6, since the number cube is numbered 1 through 6.
Therefore, the probability of rolling a prime number can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 3 / 6
Simplifying the fraction, we get:
Probability = 1/2 or 0.5
So, the probability of rolling a prime number is 1/2 or 0.5, which is equivalent to 50%.
