Probability is equal to 1
Webb13 feb. 2024 · The binomial probability formula is: P (X=r) = nCr · pʳ · (1-p)ⁿ⁻ʳ, where r is the number of successes, and nCr is the number of combinations (also known as " n choose r "). In our example we have n = 7, p = 1/12, r = 2, nCr = 21, so the final result is: P (X=2) = 21 · (1/12)² · (11/12)⁵ = 0.09439, or P (X=2) = 9.439% as a percentage.

WebbProbability Mass Function. The probability mass function, P ( X = x) = f ( x), of a discrete random variable X is a function that satisfies the following properties: P ( X = x) = f ( x) > 0, if x ∈ the support S. ∑ x ∈ S f ( x) = 1.
