**Geometric Distribution in Lottery Games**

**Understanding the Mean and Variance:**
For a geometric distribution, the mean (\(\mu\)) is given by:

\[
\mu = \frac{1}{p}
\]

And the variance (\(\sigma^2\)) is:

\[
\sigma^2 = \frac{q}{p^2}
\]

**Lottery Scenario:**

In a daily number lottery, two balls are chosen, each numbered from 0 to 9. The probability of winning this lottery is:

\[
\frac{1}{100}
\]

Let \(x\) be the number of times you play the lottery before winning for the first time.

**Tasks:**

(a) **Find the Mean, Variance, and Standard Deviation:**

Calculate these values using the provided formulas. 

(b) **Expected Plays Before Winning:**

Determine how many times you would need to play before expecting to win. Given that each play costs $1 and winners receive $600, assess whether you would expect to make a profit or incur a loss by participating in this lottery. Provide a comprehensive explanation for your analysis.
