Step 1
3, 0.4, 0.3 μ = Σ(x * P(x)) μ = (0 * 0.3) + (1 * 0.4) + (2 * 0.3) μ = 0 + 0.4 + 0.6 μ = 1 ** Show more…

The random variable x has the following probability distribution: x P(x) 0 0.30 1 0.20 2 0.50 I. If the mean of this distribution is 1.20, then the standard deviation is equal to: a/0.840 b/0.872 c/0.820 d/0.850 II. The variance of this distribution is: a/1.0 b/1.6 c/0.6 d/0.1

The random variable $X$ has the following probability distribution: $$ \begin{array}{lllll} x & 2 & 3 & 5 & 8 \\ \text { Probability } & 0.2 & 0.4 & 0.3 & 0.1 \end{array} $$ Determine the following: (a) $P(X \leq 3)$ (b) $P(X > 2.5)$ (c) $P(2.7 < X < 5.1)$ (d) $E(\mathrm{X})$ (e) $V(\mathrm{X})$
Discrete Random Variables and Probability Distributions
Poisson Distribution
A discrete probability distribution for a random variable $\bar{X}$ is given. Use the given distribution to find $(a)$ $P(X \geq 2)$ and $(b) E(X)$. $$\begin{array}{l|llll} x_{i} & 0 & 1 & 2 & 3 \\ \hline p_{i} & 0.80 & 0.10 & 0.05 & 0.05 \end{array}$$
