Question

For questions 9 – 12, consider the following probability mass function: find p(x > -2.2)?

Answer 1

Without the specific probability mass function (PMF), I can provide a general response:

To find
`\(P(x > -2.2)\)`, sum the probabilities associated with all
`\(x\)` values greater than -2.2 in the given PMF.

Step-by-step explanation:

Certainly, let's break down the explanation step by step:

1. **Define the Probability Mass Function (PMF):**

Given a probability mass function (PMF), it describes the probabilities of discrete random variables. The question mentions a specific PMF without explicitly providing its form.

2. **Clarify the Event:**

The event
`\(x > -2.2\)` refers to the probability of the random variable
`\(x\)` taking a value greater than -2.2.

3. **Probability Mass Function (PMF) Interpretation:**

In the context of a PMF, each value of
`\(x\)` has an associated probability. For
`\(x > -2.2\)`, we are interested in the cumulative probability of all values greater than -2.2.

4. **Calculate the Probability:**

The calculation involves summing up the probabilities of all individual values of
`\(x\)` that satisfy
`\(x > -2.2\)`. This might involve looking up specific probabilities from the PMF or applying relevant mathematical operations.

5. **Express the Result:**

After performing the calculation, express the result as the probability of
`\(x\)` being greater than -2.2. This could be presented as a decimal, fraction, or percentage, depending on the context and preference.

It's important to note that the specific PMF is not provided in the question, so the calculation details would depend on the actual form of the PMF. The steps outlined above are general and can be adapted based on the characteristics of the given PMF.
