Final answer:
The probability of picking a number greater than 172 from a set of numbers ranging from 1 to 25 is zero, as all numbers in the set are less than 172.
Step-by-step explanation:
The question asks about the probability of picking a number greater than 172 from a set of numbers ranging from 1 to 25. Since all numbers in this set are less than 172, the probability of picking a number greater than 172 is zero.
In a probability question like this, it's important to consider the sample space, which is all possible outcomes that can happen. The sample space in this case is the set of numbers from 1 to 25. Because none of these numbers are greater than 172, there are no favorable outcomes, resulting in a probability of 0.
