# Using Probability Distributions In Exercises 15-18, sketch a graph of the probability distribution and find each probability. x 0 1 2 3 P(x) 0.027 0.189 0.441 0.343 (a) P ( x ≥   2 ) (b) P ( x   < 2 )

(a)

To determine

To graph: The probability distribution from the following distribution table shown below and find the probability P(x2).

x0123P(x)0.0270.1890.4410.343

Explanation

Given Information:

The provided table is,

x0123P(x)0.0270.1890.4410.343

Graph:

Consider the table,

x0123P(x)0.0270.1890.4410.343

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,

Calculation:

Consider the table,

x0123P(x)0

(b)

To determine

To calculate: The value of the probability P(x<2) from the table in part (a).
