The probability of rolling something less than 5 is 1/3.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A 12-sided die can be made from a geometric solid called a dodecahedron.
The sample space is, {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
So, The probability of getting any number is 1/12.
Therefore, The probability of getting a number less than 5 is,
P(1) + P(2) + P(3) + P(4).
= 1/12 + 1/12 + 1/12 + 1/12.
= 4/12.
= 1/3.
So, The probability of getting a number less than 5 is 1/3.

Step-by-step explanation:
Answer:
5/12 5/8 5/7 5/6
Step-by-step explanation:
If we divide 5 by 12 we get 0,42
If we divide 5 by 6 we get 0.83
So we know 5/12 is less than 5/6, so we just need to order the numbers in between, and as result we get:
5/12 < 5/8 < 5/7 < 5/6

the domain is the interval of the x (input) values.
in other words, is g(x) invalid for certain x ?
it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.
the range is the interval of possible y (functional) values.
and that is clearly valid for every y between -1 and +infinity.
