Mean of a constant ‘a’ is

Variance of a constant ‘a’ is

If ‘X’ is a random variable, taking values ‘x’, probability of success
and failure being ‘p’ and ‘q’ respectively and ‘n’ trials being
conducted, then what is the probability that ‘X’ takes values ‘x’? Use Binomial Distribution

The probability that A happens is 1/3 The odds against the
happening of A are

if A , B mutually exclusive then P(A|B) =

if A , B independent events then P(A|B) =

Asynchronous sequential system ==> State updated at discrete times

The variables in the analog computer are represented by discrete signals, usually electric voltages that vary with time.

The term analog signal is sometimes substituted for continuous signal because analog computer means a computer that manipulates digital variables.

When continuous real-time signals present the variables of the process, the latter is quantized by an digital-to-analog conversion device.

The ........................ has the advantage of being easier to implement by digital components since the only thing that must be done is to change 0's into 1's and 1's into 0's.

During subtraction of two numbers by complements, the 1's complement is advantageous is that only one arithemtic addition operatoin is required.
