a twelve sided die with side labeled 1-12 will be rolled once. What is the probability of rolling a number less than 9?

1 answer:

7 0

12 possible outcomes
any number less than 9 is 8 and below
8 sides of the dice are less than 9 out of 12 total sides
8/12 is the chance you’ll roll lower than 9

2/3 or 66% chance you’ll roll a number lower than 9

Let's break this up:
let x = the number
"when I triple my number" is the same as
3x
"and add five" is the same as
+5
We combine it to get
3x+5
"I get twenty-six"
=26
combine to get
3x+5=26
Now we just solve:
subtract 5 from both sides to get
3x=21
divide by 3 to get
x=7
