When a subtraction problem is performed, the answer is the difference between the two numbers being subtracted.
Subtraction is the mathematical operation of finding the result when one quantity is taken away from another.
For example, if you have the subtraction problem 7 - 3, the answer would be 4, as you are subtracting 3 from 7, resulting in a difference of 4.
Similarly, in the subtraction problem 15 - 8, the answer would be 7, as you are subtracting 8 from 15, resulting in a difference of 7.
In general, when performing a subtraction problem, you are finding the numerical difference between two values.

What is the probability of the complement of event A?
A. 1/6
B. 1/3
C. 2/3
D. none of the above
Answer:
C) 2/3
Step-by-step explanation:
Given: { 15, 16, 17, 18, 19, 20} = 6
Event A is represents the number picked is less than or equal to 16.
Favorable outcomes = { 15, 16} = 2
Probability = The number of favorable outcomes/ The total number of possible outcomes.
Here the total number of outcomes = 6 and the number of favorable outcomes = 2
The probability of getting less than or equal to 16 P(A) = 2/6
Now we have to find the probability of complement event A.
P(A') = 1 - P(A)
= 1- 2/6
= (6 - 2)/6
= 4/6
When we simplify, we get 2/3
Therefore, the probability of complement of event A, P(A') = 2/3
Answer: C) 2/3
Hope this will helpful.
Thank you.
The probability of the complement of event A is 0, thus D. none of the above
The event A represents the numbers that are less than or equal to 16.
To find the probability of the complement of event A, we need to find the numbers that are greater than 16.
The set {15, 16, 17, 18, 19, 20} has 6 numbers and the set A has 9 numbers.
Therefore, the complement of event A has 6 - 9 = -3 numbers.
Since the number of elements in a set cannot be negative, the probability of the complement of event A is 0.
Therefore, the correct answer is D. none of the above.
