Questions & Step-by-Step Solutions
In a scenario where a set is defined by the constraints of being both a prime number and less than 10, which of the following numbers would be excluded?
Step 1: Understand what a prime number is. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
Step 2: Identify the prime numbers that are less than 10. These are 2, 3, 5, and 7.
Step 3: Look at the number '9'. Check if it is a prime number.
Step 4: Determine that '9' can be divided by 1, 3, and 9. Since it has divisors other than 1 and itself, it is not a prime number.
Step 5: Conclude that '9' is excluded from the set of numbers that are both prime and less than 10.
