Recall that in class we defined, for any set A, P(A) := {B : B ⊆ A}, which we called the power set of A.
a) (10) Show that, if a set A has n elements (where n ∈ {0, 1, 2, 3, 4, . . .}), P(A) has exactly 2 n elements.
b) (10) Use #4(any infinite set S has a countably infinite subset) to show that, if A is an infinite set, P(A) is uncountable.

An engineering system consisting of n components is said to be a
k-out-of-n
system (k ≤ n) if the system functions if and only if at least k of
the n components
function. Suppose that all components function independently of
each other.
(a) If the ith component functions with probability Pi , i=1, 2, 3,
4, compute
the probability that a 2-out-of-4 system functions.
(b) Repeat (a) for a 3-out-of-5 system.

x = 7;
y = x + 1;
z = x % (y – 2) + 4;
y = (y + z ) % (x + 4) ;
w = (x * y) / (z – 3);
x = x + x;
u = w - 3;
t = z + (x + y + 2) % w;
