A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling

Nastasia [14]

<h3>Answer: 1/12</h3>

This is because there's one side we want (that's labeled "8") out of 12 sides total. This is of course if each side is equally likely.

Side note: this 12-sided die is known as a dodecahedron.

True [87]

Answer: OPTION B

Step-by-step explanation:

Let be "x" the acceptable lengths for the rod.

You know that the ideal length of the metal rod is 30.5 centimeters and the measured length may vary from the ideal length by at most 0.015 centimeters.

Therefore, knowing this, you can say that the acceptable lengths must be:

$30.5cm-0.015cm\leq x\\\\30.485\leq x$

$x \leq 30.5cm+0.015cm\\\\x\leq 30.515$

Therefore, the range of acceptable lengths for the rod is the following:

$30.485\leq x\leq 30.515$

This range matches with the one shown in the option B.
