Answer 1

Answer:

16 is the correct answer.

Step-by-step explanation:

since the number of subsets is given by the formula 2^n . the given set has 4 elements ,thus n=4. so the answer is 2^4=16

Answer 2

Answer:

The total number of proper subsets is given by formula.

$\large\red{\boxed{ no. (proper subsets) =2^{n}-1}}$

where n is the cardinal number of sets.

______________________________________

Here cardinal number is 4,so

Number of proper subsets =

=$2^{4}-1$

=$16-1$

=$15$
