Question

Find the sample space in choosing an integer from the interval [1, 9].{2, 3, 4, 5, 6, 7, 8}{1, 2, 3, 4, 5, 6, 7, 8, 9}{1, 2, 3, 4, 5, 6, 7, 8}{2, 3, 4, 5, 6, 7, 8, 9}

Answer 1

Given the Interval:

$\lbrack1,9\rbrack$

You need to remember that, by definition, a Sample Space is a collection of all the possible outcomes of a random experiment.

In this case, you have a closed interval (because it has square brackets). Therefore, the Sample Space contains all the Integer Numbers from 1 to 9, including the numbers 1 and 9:

$\lbrace1,2,3,4,5,6,7,8,9\rbrace$

Hence, the answer is: Second option.
