Problem 2: The random variable N has PMF PN(n) = { c(2/3)^n , n = {1, 2, 3, ...} 0, otherwise. (a) What is the value of the constant c? (b) What is the value of P[N ? 2]? (c) What is the value of P[N ? 2]?

Step 1
This means that the sum of all probabilities for all possible values of N must equal 1. However, the problem does not provide enough information to determine the value of the constant c. We would need to know the probabilities associated with each value of N to Show more…

Let $Y_{1}, Y_{2}, Y_{3}, \ldots Y_{n}$ be independent standard normal random variables. a. What is the distribution of $\sum_{i=1}^{n} Y_{i}^{2} ?$ b. Let $W_{n}=\frac{1}{n} \sum_{i=1}^{n} Y_{i}^{2} .$ Does $W_{n}$ converge in probability to some constant? If so, what is the value of the constant?
