Question

please tell this with full explanation I will mark you as brainly
question is what is the total number of proper subsets of set consisting of n elements

Answer 1

• THE NO. OF SUBSETS =2^n
• the no. of proper subset=2^n - 1

if there are 8 elements in a set

then the no. of subsets=2^8=256

the no. of proper subset=2^8 -1

=256-1=255
