Question

Dice Rolls and the Binomial Model

Scenario

A casino analyst models dice rolls to understand outcome probabilities for marketing promotions.

Question

You roll a fair six-sided die 10 times. Let X be the number of sixes observed.

Compute:

P(X = 3) — the probability of observing exactly 3 sixes.
E[X] — the expected number of sixes in 10 rolls.
SD[X] — the standard deviation of the number of sixes.

Hint: Model X with a Binomial distribution: n = 10, p = 1/6.
