thank you for your help, but i need to plot normal gaussian distribution random variable if the result is head, means the plot represnts mixed random variable the first one is discrete (tossing the coin) and the
连续型随机变量(continuous random variable):如果随机变量X的所有可能取值不可以逐个列举出来,而是取数轴上某一区间内的任一点的随机变量。 概率密度函数用数学公式表示就是一个定积分(反向求导函数)的函数,定积分在数学中是用来求面积的,而在这里,你就把概率表示为面积即可! 左边是F(x)连续型随机变量分布函数画出...

The Standard Normal Distribution The normal distribution with parameter values μ=0 and σ=1 is called astandard normal distribution. A random variable that has a standard is called astandard normal random variableand will be denoted byZ. Percentiles of the Standard Normal Distribution For any p b...
Similar to the discrete-valued case, the expected value of a continuous random variable x is given as: 与离散值随机变量的情况类似,连续随机变量x的期望值表示为: E[x] = \int^∞_{-\infty} xp(x)dx. Now consider some function f(x), where p(x) is the probability distribution function ...
The Uniform Distribution (also called the Rectangular Distribution) is the simplest distribution.It has equal probability for all values of the Random variable between a and b:The probability of any value between a and b is pWe also know that p = 1/(b-a), because the total of all ...
