Question 2 • Algebra 2 with Probability

A certain board game uses a spinner divided into 12 equal regions showing the numbers 1 – 12 If the spinner is used three times, what is the probability that the result is a number 10 or larger all three times?

Answer
A
open paren 10 over 12 close paren cubed
B
open paren 2 over 12 close paren cubed
C
open paren 3 over 12 close paren cubed
D
open paren 1 over 12 close paren cubed

Explanation

The numbers 10, 11, and 12 meet the condition, so the probability on one spin is 3/12. The three spins are independent, so multiply the probability for each spin: (3/12)³. This is choice C, “(3 over 12) cubed.”
