Answer:
c) 12
Step-by-step explanation:
To find the total number of ordered pairs of whole numbers where the first number is between 17 and 19 and the second number is between 7 and 10, you can simply multiply the number of options for each number.
The options for the first number are {17, 18, 19} which gives 3 options.
The options for the second number are {7, 8, 9, 10} which gives 4 options.
Therefore, the total number of ordered pairs is 3 * 4 = 12.
So, the correct answer is:
c) 12
