Question
Answer these 2 math question. Each picture is a different math problem
The image shows a problem statement and a diagram, which are part of an educational activity for finding the area under the standard normal curve. **Problem Statement:** "Find the area of the shaded region under the standard normal curve." There is a link provided: "Click here to view the standard normal table." **Prompt:** "The area of the shaded region is [ ] (Round to four decimal places as needed.)" **Diagram Explanation:** The diagram on the right displays a standard normal distribution curve with a shaded area. The curve represents a bell-shaped graph typical of a normal distribution. The shaded region is to the right of the vertical line at \( z = 1.11 \). This line indicates the \( z \)-score for which the area to the right is of interest. At the bottom, there is a "Next" button indicating progression after inputting the solution.

**Title: Identifying a Probability Distribution** **Table of Distribution:** The table below provides values of a variable \( x \) and their corresponding probabilities \( P(x) \). \[ \begin{array}{c|cccccc} x & 0 & 1 & 2 & 3 & 4 & 5 \\ \hline P(x) & \frac{1}{10} & \frac{1}{10} & \frac{1}{25} & \frac{1}{50} & \frac{1}{100} & \frac{1}{20} \\ \end{array} \] **Question:** Is the probability distribution a discrete distribution? Choose the correct answer below. **Options:** - **A.** No, because the total probability is not equal to 1. - **B.** No, because some of the probabilities have values greater than 1 or less than 0. - **C.** Yes, because the distribution is symmetric. - **D.** Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. **Correct Answer:** - **D.** Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. **Explanation:** For a set of probabilities to define a valid probability distribution, two main conditions must be satisfied: 1. The probabilities for all potential outcomes must sum to 1. 2. Each individual probability must be between 0 and 1, inclusive. In this case, option D correctly identifies that the given probabilities meet the criteria for a discrete probability distribution.
