Chapter 13: Q 9. (page 847)

Write down all the subsets of $\{a, b, c, d\}$ .

Short Answer

Expert verified

The subsets are $\emptyset, \{a\}, \{b\}, \{c\}, \{d\}, \{a, b\}, \{a, c\}, \{a, d\}, \{b, c\}, \{b, d\}, \{c, d\}, \{a, b, c\}, \{a, b, d\}, \{a, c, d\}, \{b, c, d\}, \{a, b, c, d\}$ .

Step by step solution

Step 1. Given Information.

Write down all the subsets of $\{a, b, c, d\}$ .

Step 2. Subsets.

The total number of subsets are $2^{n}$ where $n = 4$ .

So, number of subsets are $2^{4} = 16$ .

0 elements - $\emptyset$ .

1 elements - $\{a\}, \{b\}, \{c\}, \{d\}$ .

2 elements - localid="1646976761171" $\{a, b\}, \{a, c\}, \{a, d\}, \{b, c\}, \{b, d\}, \{c, d\}$ .

3 elements - localid="1646976797520" $\{a, b, c\}, \{a, c, d\}, \{a, b, d\}, \{b, c, d\}$ .

4 elements - $\{a, b, c, d\}$ .
