Web3. The probability of any single value from a continuous distribution is zero. This is what makes a continuous distribution different from a discrete distribution. The normal distribution is a continuous distribution and hence the probability of getting exactly 1.23 is zero. Further, the probability of getting either 1.23 or -1.23 is also zeo. WebSep 26, 2024 · P ( log ( R) ≤ log ( 0.96)) log is natural logirthm in this case. We know that l o g ( R) follows normal distribution so by normalizing value of l o g ( 0.96) we can get our probability Z = x − μ σ plugging in values gives us: Z = log ( 0.96 − 5.1) 3 ≈ − 1.71360 Z is standardized normal.
