Step-by-step explanation: on edgunity
The key to solving this is knowing that the sum of probability distribution is always 1.
Out of all the tables, only the table below satisfies this condition.
A 2-column table labeled Probability Distribution B has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled P (x) with entries 0, 0.45, 0.16, 0.39.
Option C: , but probability cannot be negative
I just answered the question and got it right
Probability distribution B
Probabilities cannot be negative numbers. This means we can exclude distributions A and C.
Probability can be a maximum of 1.0. This means we can eliminate distribution D.
This leaves distribution B.
We can double check by finding the sum of the distribution. The sum of a probability distribution is 1.0. Adding these probabilities together, we have
0+0.45+0.16+0.39 = 1.00
B is correct.
The answer is the second option, just took the test.
answer is B
