What is the mean for a beta distribution?

  1. Mean = (2O + ML + P)/4

  2. Mean = O + ML + P

  3. Mean = (O + 2ML + P)/4

  4. Mean = (O + 4ML + P)/6

The correct answer is: Mean = (O + 4ML + P)/6

In a beta distribution, the mean is calculated using the formula Mean = (O + 4ML + P)/6. This formula takes into account the values of the variables O, ML, and P and then divides the sum by 6 to determine the mean. This formula is specific to the beta distribution and is used to find the central tendency of the distribution.
