Final answer:
-7 is indeed an odd number. The concepts of being odd and even apply to both positive and negative integers. Separately, when discussing probability, k = 0 represents the probability of an impossible event such as rolling a 7 on a standard die.
Step-by-step explanation:
Yes, -7 is an odd number because it cannot be evenly divided by 2. Whether a number is odd or even is determined by its remainders when divided by 2. Negative numbers follow the same rules for odd and even as positive numbers. For example, both 7 and -7 leave a remainder of 1 when divided by 2, therefore, they are both odd. As for the second part of your question, there is no clear correlation between the values provided in the context (-3, -2, -1, 0) and the original question about the property of being odd. However, if we are looking for a value of k associated with the concept of probability (as suggested by some of the provided context), k = 0 would be the probability of an impossible event, such as rolling a 7 on a standard die.
