Question 1164008: Goodnight please help with these questions,
Fidelity records the number of X-Trails sold each day. This data is used in calculating the following probability distribution of daily sales:
x P(x)
0 0.1
1 0.1
2 0.2
3 0.2
4 0.3
5 0.1
a. Verify that this [P(x)] is a probability distribution
You can put this solution on YOUR website!
The sum of all probabilities for all possible values must equal 1. Furthermore, the probability for a particular value or range of values must be between 0 and 1.
Since your example has probabilities that are all between zero and one, then it is a probability distribution function if
