Introduction

Probability distribution tables are a crucial tool in statistics and mathematics, used to represent the probability of different outcomes in a random experiment. These tables provide a visual representation of the probability of each outcome, making it easier to understand and analyze the data. In this article, we will explore how to use a probability distribution table to answer a question, and provide a step-by-step guide on how to interpret the results.

What is a Probability Distribution Table?

A probability distribution table is a table that lists the possible outcomes of a random experiment, along with their corresponding probabilities. The table typically consists of two columns: one for the outcome (X) and one for the probability (P). The probability column represents the likelihood of each outcome occurring.

Example Probability Distribution Table

X	P
1	0.04
2	0.07
3	0.22
4	0.22
5	0.22
6	0.12
7	0.11

Interpreting the Probability Distribution Table

To interpret the probability distribution table, we need to understand the meaning of each value in the table. The value in the X column represents the outcome, while the value in the P column represents the probability of that outcome occurring.

Outcome (X): The outcome is the value that we are interested in. In this case, the outcomes are the numbers 1 through 7.
Probability (P): The probability is the likelihood of each outcome occurring. The probability is represented as a decimal value between 0 and 1.

Understanding the Probability Values

The probability values in the table represent the likelihood of each outcome occurring. The higher the probability value, the more likely the outcome is to occur.

High Probability Values: The outcomes with high probability values (e.g., 0.22) are more likely to occur.
Low Probability Values: The outcomes with low probability values (e.g., 0.04) are less likely to occur.

Using the Probability Distribution Table to Answer a Question

Now that we have a basic understanding of the probability distribution table, let's use it to answer a question. The question is: What is P(1)?

Step 1: Identify the Outcome

The outcome we are interested in is X = 1.

Step 2: Find the Probability

The probability of the outcome X = 1 is 0.04.

Step 3: Answer the Question

The answer to the question is 0.04.
