(a)
To graph: The probability distribution and find the probability
Given Information:
The probability distribution:
Graph:
Consider the provided probability distribution.
Use the ti83 graphing calculator to construct the graph to represent this probability distribution.
Step 1: Open the ti83 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 is obtained as,
For any random variable X, and specific values a and b, the probability
Consider the provided probability distribution
