Question 1129979: I have a question regarding probability distribution.
If given a few choices, and after adding them up:
Choice 1 equaled 1.1
Choice 2 equaled 1.1
Choice 3 equaled 1.0
Choice 4 equaled 1.0
If I understand this correctly,a probability must be a number between 0 and 1, inclusive. For probability distribution, the sum of the probabilities must be 1.
With that in mind, Choice 3: 0.5-0.2+0.3+0.4 would not be correct because one of the numbers is negative?
Where,
Choice 4: 0.1+0.6+0+0.3would be a solution because it falls within all specified parameters?
Am I interpreting this correctly?
Thank you!
