Statistics. Please help.
Hi, the topic is Probability Density Function of a random variable.
For each of the following, find the constant c so that p(x) satisfies the condition of being a probability density function of a random variable X: I. p(x) = c(2/3)^x, x ∈ N II. p(x) = cx, x ∈ {1,2,3,4,5,6} I've been figuring this for couple of days. |
