# For the discrete probability distribution described by Pr(x) = x/16, x = 1, 2, 3, 4, 6, find the(a) mean.(b) variance.(c) standard deviation.

(a)

To determine

To calculate: The mean of the discrete probability distribution Pr(x)=x16 where, x=1,2,3,4,6.

Explanation

Given Information:

The discrete probability distribution is Pr(x)=x16 where, x=1,2,3,4,6.

Formula Used:

The mean is the expected value of the probability distribution x is,

μ=E(x)=(xPr(x))

Calculation:

Consider the discrete probability distribution,

Pr(x)=x16

Where, x=1,2,3,4,6.

The probability distribution can be written as,

 x Pr(x)=x16 1 116 2 216 3 316 4 4<

(b)

To determine

To calculate: The variance of the probability distribution Pr(x)=x16 where, x=1,2,3,4,6.

(c)

To determine

To calculate: The standard deviation of the probability distribution Pr(x)=x16 where, x=1,2,3,4,6.
