Math Problem Statement
Can the following table be a probability distribution? 1 0.0086 2 0.2971 3 0.1435 4 0.3417 5 0.2091
no yes
Solution
To determine if a table can represent a probability distribution, it must meet two key criteria:
- Each probability must be between 0 and 1, inclusive.
- The sum of the probabilities must equal 1.
Let's check both criteria:
-
All probabilities in the table are between 0 and 1:
- are all within the range .
-
Sum of the probabilities:
Since the sum equals 1, yes, this can be a probability distribution.
