For the following distribution,

x: 0,1,2,3

p(x): 0.027, 0.189, 0.441, 0.343

what is the variance of the distribution?

2.1

0.63

3.9

2.754

Option B) 0.63

Step-by-step explanation:

We are given the following in the question:

X:            0          1           2            3

P(x):   0.027   0.189    0.441     0.343

We have to find the variance for the given discrete probability distribution.

The variance of given distribution is 0.63

then i will answer

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
