Math Problem Statement
solution for question 20
Solution
The table you've provided represents a discrete probability distribution for the random variable . The values of range from 0 to 5, with corresponding probabilities for each value.
Here is the data:
0 | 1 | 2 | 3 | 4 | 5 | |
---|---|---|---|---|---|---|
0.10 | 0.41 | 0.19 | 0.15 | 0.10 | 0.05 |
This is a discrete probability distribution, which follows these key properties:
- The sum of all probabilities should be 1.
- Each probability is between 0 and 1 (inclusive).
Sum of Probabilities:
Thus, the given distribution is valid.
