WebTo calculate a probability, the probability density is multiplied by a range of values. For example, the probability that the signal, at any given instant, will be between the values of 120 and 121 is: (121 - 120) × 0.03 = 0.03. The probability that the signal will be between 120.4 and 120.5 is: (120.5 - 120.4) × 0.03 = 0.003 , etc. WebMar 24, 2024 · The major difference between statistics and machine learning is that statistics is based solely on probability spaces.
