An adventure game has a number cube with 12 equal-size faces, each labeled with a number from 1 to 12. What is the probability of rolling a 4 or a multiple of 3? Express your answer in simplest form.

OpenStudy (myth1111):

Right, so, what are the multiples of 3 that equal 12 or less

OpenStudy (emogirlatemoooocow):

Less than 12 or greater than 12 ?

OpenStudy (myth1111):

The question asks for the chance of rolling a multiple of 3 or the number 4, so that means 5 sides.

OpenStudy (myth1111):

Since we have 5 possible sides to roll, and 12 total sides, what's the answer?

OpenStudy (anonymous):

The answer is 42

OpenStudy (emogirlatemoooocow):

soo\[\frac{ 4 }{ 42 }\] ?

OpenStudy (myth1111):

It's 5/12 lol

OpenStudy (emogirlatemoooocow):
