For the senior-class election, 8 candidates are running for president and 6 for vice-president. Use the Fundamental Counting Principle to calculate the total number of class officer combinations available.

a. 14
b. 36
c. 48
d. 64

To calculate the total number of class officer combinations, we need to multiply the number of candidates running for president (8) by the number of candidates running for vice-president (6).

Using the Fundamental Counting Principle, the total number of class officer combinations available is 8 * 6 = 48.

Therefore, the correct answer is c. 48.
