## In Exercises 3 and 4, sketch a graph of the probability distribution and find each probability. x 1 2 3 4 P(x) 3 16 7 16 1 16 5 16 (a) P ( x < 3 ) (b) P ( x ≥ 2 )

(a)

To determine

To graph: The probability distribution:

 x 1 2 3 4 P(x) 316 716 116 516

and calculate the probabilities P(x<3).

### Explanation of Solution

Given Information:

The probability distribution:

 x 1 2 3 4 P(x) 316 716 116 516

Graph:

Consider the provided probability distribution.

 x 1 2 3 4 P(x) 316 716 116 516

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 and press 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

X List: L1

Freq: L2

Step 4: Press the GRAPH key

(b)

To determine

To graph: The probability distribution:

 x 1 2 3 4 P(x) 316 716 116 516

and calculate the probabilities P(x2).
