Using Probability Distributions In Exercises 11 and 12, sketch a graph of the probability distribution and find each probability.

x 1 2 3 4 5
P ( x ) 1 18 7 18 5 18 3 18 2 18

(a) P ( 2 x 4 )

(b) P ( x 3 )

(a)

To determine

To graph: The probability distribution and find the probability P(2x4).

x 1 2 3 4 5
P(x) 118 718 518 318 218

Explanation of Solution

Given Information:

The probability distribution:

x 1 2 3 4 5
P(x) 118 718 518 318 218

Graph:

Consider the provided probability distribution.

x 1 2 3 4 5
P(x) 118 718 518 318 218

Use the ti-83 graphing calculator to construct the graph to represent this probability distribution.

Step 1: Open the ti-83 graphing calculator.

Step 2: Press [STAT] [ENTER] key and enter the data in L1 and L2.

Step 3: Press the [2ND] and select “Y=”. Use the arrow keys and select the Plot 1:ON

Type: Select Bar Graph

Step 4: Press the [GRAPH] key.

The bar graph of the probability distribution obtained as,

Consider the provided probability distribution

(a)

To determine

To graph: The probability distribution and the probability P(x3) by using data below.

x 1 2 3 4 5
P(x) 118 718 518 318 218
