Answer:
0.14% probability of a person guessing the right combination
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the numbers are selected is important. For example, 1,3,2 is a different combination than 3,1,2. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
Desired outcomes:
One right combination, so 
Total outcomes:
10 numbers from a set of 3. So
What is the probability of a person guessing the right combination?
0.14% probability of a person guessing the right combination

The expression that is equal to -4 is D 16/-4 which means option D is correct. ( it should be noted that option D is not written properly)
<h3>Why is that 4 is equals to 16
/-4?</h3>
In a mathematical expression when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.
In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence expression that is equal to -4 is 16/-4 which is means optionD is correct.
Therefore, option C is correct.
