Question
In the probability distribution to the right, the random variable X represents the number of hits a baseball player obtained in a game over the course of a season. Complete parts (a) through (1) below. P(x) O 0.1666 t 1 0.3347 2 0.2857 0.1495 0.0383 5 0.0252 (a) Verify that this is a discrete probability distribution. This is a discrete probability distribution because all of the probabilities are between 0 and 1, inclusive, and the of the probabilities is 1. sum (Type whole numbers. Use ascending order.) (b) Draw a graph of the probability distribution. Describe the shape of the distribution. Graph the probability distribution. Choose the correct graph below O A. O B C. OD. 0.4- 0.4 0.4 0.4- 0.3- 0.3- 0.2- 0.3- 0.3- 0.2- 0.1- Q 0.2- 0.2- 0.1- 0.1 0.1- ói234 5 0123 4 5 Number of Hits 0123 4 6 0123 4 5 Number of Hits Number of Hits Number of Hits Describe the shape of the distribution.
