A random process is a collection of random variables indexed by a parameter, usually time. In electrical engineering, random processes are used to model and analyze signals and systems that vary randomly over time.
P(incorrect) = 1 - (0.9^2 + 0.1^2) = 0.19
The mean of the output signal Y(t) is given by: In electrical engineering, random processes are used to
The probability that X(t) > 2 is given by:
A coin is tossed 100 times. What is the probability of getting exactly 50 heads?

A source generates a random sequence of bits (0s and 1s) with a probability of 0.6 for a 1 and 0.4 for a 0. What is the probability that a single bit is in error when transmitted over a noisy channel with a probability of error 0.1?
Var[Y(t)] = Var[X(t)] * (1 / (2 * pi) ) * ∫|H(jω)|^2 dω = 1/2
