    Inference & Hypotheses (Lesson 6/6)

    Binomial & Poisson Tests

    1 / 6

    Discussion

    A ​6​-sided die is rolled ​40​-times, and a ​1​ is obtained ​11​ times. Let ​X​ be the number of ​1​s rolled.

    (a)

    State the distribution of ​X​ assuming the die is fair.

    Solution:

    This is a classic binomial distribution:

    ​
    X∼B(40,61​)
    ​
