Find the mean of the probability distribution
WebThe random variable x is the number in the group who say that they would feel comfortable in a self-driving vehicle. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. WebJan 21, 2024 · For a general discrete probability distribution, you can find the mean, the variance, and the standard deviation for a pdf using the general formulas. μ = ∑ x P ( x), σ 2 = ∑ ( x − μ) 2 P ( x), and σ = ∑ ( x − μ) 2 P ( x) These formulas are useful, but if you know the type of distribution, like Binomial, then you can find the ...
