Question: What is the odds ratio of the number 7218 appearing among all the possible 4-digit numbers starting from 1000 to 9999?

To find the odds ratio, we need to calculate the ratio of the number of favorable outcomes (where 7218 appears) to the number of possible outcomes (all 4-digit numbers). There are 9000 possible outcomes since we exclude numbers below 1000 and above 9999. To determine the favorable outcomes, we consider that there is only one instance of the number 7218. Hence, the odds ratio is 1/9000. So, the answer is: The odds ratio of the number 7218 appearing among all possible 4-digit numbers starting from 1000 to 9999 is 1 in 9000.

Math Question: If the number 7218 is multiplied by 3 and then divided by 2, what is the result?

To find the result, we first multiply 7218 by 3, which gives us 21654. Then, dividing this number by 2 gives us the final result, which is 10827.

What is the product of 7218 and its prime factors excluding 1?

The prime factors of 7218 are 2, 7, and 173. The product of these prime factors is 2 * 7 * 173 = 2422.
