Answer 2

Answer:        1/12

Step by step solution:

If you have a cube that is 12 sided, this is how you will go about calculating the probability of rolling a 5:

            Formula for calculating probability:

            Probability of an outcome A =

     Number of favourable outcomes of A / Number of possible outcomes

       P ( A )  = number of favourable outcomes to A / total number of outcomes

⇒ The number of times 5 can appear when you roll the 12 sided cube once is one time   =  1

⇒ The total number of possible outcomes is 12 - meaning you can roll any number between 1 - 12 when you roll the dice once.   = 12

Therefore the probability of rolling 5  = 1 /12

 Probability = 1 / 12
