Question

Nika rolls an 8-sided cube with faces numbered 1 through 8. Which of the following statements is true?

P(even number) = ⅛
P(odd number) = ½
P(number less than 8) = 1
P(the number 9) = 1

Answer 1

Answer: Statement 2 (P(odd number) = 1/2) is true

Explanation:

Statement 1: there are 4 even numbers (2, 4, 6, 8) so therefore a 1/2 chance, not a 1/8. [FALSE]

Statement 2: there are 4 odd numbers (1, 3, 5, 7) so therefore a 1/2 chance, so this is true. [TRUE]

Statement 3: 8 is the biggest number, so there are 7, not 1, numbers less than it. [FALSE]

Statement 4: there is no 9 on an 8 sided cube. [FALSE]
