Question

A=red and blue find the total number subsets of set A
A. 1
B. 2
C. 3
D. 4
E. 5
F. 6
Best answer

Answer 1

To find the total number of subsets of a set, you can use the formula \( 2^n \), where \( n \) is the number of elements in the set.

In your set \( A \), which consists of the elements "red" and "blue", there are 2 elements.

So, the total number of subsets is:
\[
2^2 = 4
\]

The subsets of set \( A = \{ \text{red}, \text{blue} \} \) are:
1. The empty set: \( \{\} \)
2. The subset containing "red": \( \{\text{red}\} \)
3. The subset containing "blue": \( \{\text{blue}\} \)
4. The subset containing both "red" and "blue": \( \{\text{red}, \text{blue}\} \)

Therefore, the total number of subsets is 4.

The correct answer is:
**D. 4**
