Question

Table below gives the probability distribution of a discrete random variable
X. Find the probability that X takes a value less than 3
.(Enter the answer correct to two decimals accuracy).

Answer 1

Step-by-step explanation:

Associated to each possible value x of a discrete random variable X is the probability P(x) that X will take the value x in one trial of the experiment.

...

Compute each of the following quantities.

a.

P(0).

P(X>0).

P(X≥0).

P(X≤−2).

The mean μ of X.

The variance σ2 of X.

The standard deviation σ of X.
