Experiment: Experiment is a process of observation. Here, we will use E to denote it.
Sample Space: The set of all possible outcome of the experiment. We will use S to denote it.
E1: Toss a true coin three times and observe the sequence of heads and tails.

In hamming code, there are 4 bits of original data & 3 bits of redundant bits. N = M+K, here, N = codewords/full message, M=Datawords/Original Message & K = Redundant bits. So, N = 4+3, = 7 bits.
Burst Error: A burst error means when 2 or more bits in the data unit have changed.
Burst Error Length: The length from starting left-end corrupted bit to right-end corrupted bit in a data unit is called Burst Error Length.
