The following is a probability distribution function for X, with range 0, 1, 2, 3: P(X = 0) = 0.1; P(X = 1) = 0.3; P(X = 2) = 0.4; P(X = 3) = 0.2. Compute E(X). Round your answer to one decimal place.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
