How many positive three-digit integers have the hundreds digit equal to 7 and the units (ones) digit equal to 1?
Lina20 [59]

Using the Fundamental Counting Theorem, it is found that there are 10 positive three-digit integers have the hundreds digit equal to 7 and the units (ones) digit equal to 1.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

The number of options for each selection are given as follows, considering there are 10 possible digits, and that the last two are fixed at 7 and 1, respectively:

n_1 = 10, n_2 = n_3 = 1

Hence, the number of integers is given by:

N = 10 x 1 x 1 = 10.
