Example of a Random Variable A typical example of a random variable is the outcome of a coin toss. Consider a probability distribution in which the outcomes of a random event aren't equally likely to happen. Y could be 0, 1, or 2 if the random variable Y is the number of heads we ...
1. Discrete Random Variables:Discrete random variables can only take on a finite or countable number of values. For example, the number of heads obtained when flipping a coin three times is a discrete random variable because it can only have the values 0, 1, 2, or 3. 2. Continuous Rando...

More generally, we can consider a random variable that takes values in an interval ,and again assume that any two subintervals of the same length have the same probability. Example 3.2. Piecewise Constant PDF. What is the PDF of the driving time,viewed as a random variable ? Generalizing...
EXAMPLE 15.6a (Generating an Exponential Random Variable) Let F(x) = 1 - e-λx, x≥ 0 be the distribution function of an exponential random variable with parameterλ. Then F–1(u) is that value x such that u=F(x) = 1 - e-λx or, equivalently, e-λ...
. let z be a non-negative random variable. the following conditions are equivalent: (i) there exist \(k_1,l_1>0\) such that $$\begin{aligned} \mathbb {p}(z\ge t) \le k_1 e^{- t^r/ l_1} \quad \text {for all } t\ge 0. \end{aligned}$$ (ii) there exists \(k_...

It’s well-suited for both regression and classification problems. The output variable in regression is a sequence of numbers, such as the price of houses in a neighborhood. The output variable in a classification problem is usually a single answer, such as whether a house is likely to sell...
4.4 End of Chapter ProblemsProblem Choose a real number uniformly at random in the interval [2,6][2,6] and call it XX. Find the CDF of X, FX(x)FX(x). Find EXEX. Problem Let XX be a continuous random variable with the following PDF ...
You use the set directive to change a mutable variable's value. The ResultArrayAsInt function, from the default Microsoft.Quantum.Convert namespace, converts the bit string to a positive integer. Finally, you add an entry point to the program. By default, the Q# compiler looks for a Main...
