Final answer:
To find the probability of selecting an even number from the given set, divide the number of even numbers by the total number of numbers in the set.
Step-by-step explanation:
To find the probability of selecting an even number from the given set, we need to determine the number of even numbers in the set and divide it by the total number of numbers in the set.
The given set is (1, 2, 5, 10, 25, 30, 36). Among these numbers, 2, 10, 30, and 36 are even numbers.
Therefore, there are 4 even numbers in the given set.
Since there are a total of 7 numbers in the set, the probability of selecting an even number is 4/7.
