Question

For any set A,(A1 ) 1 is equal to

Answer 1

Answer:

$\huge\underline\mathbb{MARK \: \: AS \: \: BRANLIST}$

The total no of subsets of A is the cardinality of the power set of A.

So, if ∣A∣=n then ∣P(A)∣=2

n

.

Therefore total no of subsets of A is 2

n

.

Similarly,

The even number of events is given by, 2

n−1
