Question 4 (1 point)
Find the theoretical probability of rolling two cubes and getting a sum of 3.


Sagot :

Answer:

The theoretical probability is 1/18

Step-by-step explanation:

Firstly, we need to know the total number of possible results

By rolling two cubes, there are a total of 36 possible results

Now, the sum of 3 can be gotten by the addition of 1 to 2 or 2 to 1

If we have 1 on the first cube and 2 on the second, we have the correct sum

we can also have 2 on the first cube and 1 on the second

This gives a total of 2 possible ways of getting 3

The probability can be calculated by dividing the number of ways to get 3 by the total number of possible results

we have this simply as 2/36 = 1/18
