fix) I Ox3 8.3x2 + 2.295x - 0.21141 = 0 has a root at x = 0.29. Use Newton's method with an initial approximation xo = 0.28 to attempt to find this root. Explain what happens.

5.4 Discrete Random variables and Probability distributions (Related to variables and relative frequency distribution) Random variables: A random variable is a quantitative variable whose values depend on chance. • Typically, we use capital letters towards the end of the alphabet to represent random variables (X, Y, Z). • It is important to note that in the context of random variables, an eventis associated with the random variable taking on a particular value EX: Suppose our experiment involves tossing a fair and balanced six-sided die. We can define a random variable X to keep track of the face of the die that shows up on a single roll. • So our random variable X can be realized as several different values • This is denoted as X=x
