The probability of rolling a number that is odd or even when rolling a fair, six-sided die is 1.
Step-by-step explanation:
When rolling a fair, six-sided die, there are three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5).
To find the probability of rolling a number that is odd or even, we need to add the probabilities of both events. The probability of rolling an odd number is 3/6 or 1/2, and the probability of rolling an even number is also 3/6 or 1/2.
So, the probability of rolling a number that is odd or even is 1/2 + 1/2 = 1.
