You grab two books at random off a shelf. Let X be the number of those two books that you have previously read. Determine all possible values for the random variable X.

X = (0 , 1 , 2)

Step-by-step explanation:

Random Variable is a variable whose value depends on outcomes of a random phenomena. There are two types of random variables :

Given : I grabbed two books randomly off shelf ; X = Random Variable values of 'number of books read'.

So, the number of books that could have already been read : could be- 0 books, or 1 book, or  2 books; out of total 2 books picked up.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
