In Exercises 3 and 4, sketch a graph of the probability distribution and find each probability.

x 7 8 9 10 11
P(x) 0.21 0.13 0.19 0.42 0.05

(a) P ( 7 x 10 )

(b) P ( x > 8 )

(a)

To determine

To graph: The probability distribution:

x 7 8 9 10 11
P(x) 0.21 0.13 0.19 0.42 0.05

and calculate the probabilities P(7x10).

Explanation of Solution

Given Information:

The probability distribution:

x 7 8 9 10 11
P(x) 0.21 0.13 0.19 0.42 0.05

Graph:

Consider the provided probability distribution.

x 7 8 9 10 11
P(x) 0.21 0.13 0.19 0.42 0.05

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 7 8 9 10 11
P(x) 0.21 0.13 0.19 0.42 0.05

and calculate the probabilities P(x>8).
