To determine the result of the expression 15 ÷ 3 + 4 × 2, we need to follow the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

First, we handle the division and multiplication before performing the addition.

1. Begin with the division:

- 15 ÷ 3 equals 5.

2. Next, move to the multiplication:

- 4 × 2 equals 8.

At this point, we have simplified the expression to 5 + 8.

3. Finally, we perform the addition:

- 5 + 8 equals 13.

Thus, the final result of the expression 15 ÷ 3 + 4 × 2 is 13. This is why the correct answer is the one that reflects this calculation.
