Mrs. Chauvet has an unfair number cube that lands with
6 facing up 40% of the time.
Let X = the number of times that she rolls a 6 among 3
trials.
Use the tree diagram to answer the questions.
For how many of the outcomes does X = 0, meaning
the outcome has no 6s?
For how many of the outcomes does X = 1, meaning
the outcome has exactly one 6?
For how many of the outcomes does X = 2, meaning
the outcome has exactly two 6s?
For how many of the outcomes does X = 3, meaning
the outcome has exactly three 6s? V
