Hello Let's first find set A A = {x: x is a prime number less than 20} Prime numbers less than 20 are 2, 3, 5, 7, 11, 13, 17, 19 So, A = {2, 3, 5, 7, 11, 13, 17, 19} Now, Number of subsets are

Answer of this question

If A = {x:x is a prime number less than 20} find the number of subsets

Hello

Let's first find set A

A = {x: x is a prime number less than 20}

Prime numbers less than 20 are 2, 3, 5, 7, 11, 13, 17, 19

So, A = {2, 3, 5, 7, 11, 13, 17, 19}

Number of Subsets = 2ⁿ

Number of Subsets = 2⁸ = 256
