Binomial distribution method

WebWe can calculate the exact probability using the binomial table in the back of the book with n = 10 and p = 1 2. Doing so, we get: P ( Y = 5) = P ( Y ≤ 5) − P ( Y ≤ 4) = 0.6230 − 0.3770 = 0.2460.

WebSep 9, 2015 · It makes no difference if the distribution from which you wish to sample is continuous or discrete. For example, suppose you wish to sample from X ∼ Binomial ( n = 5, p = 0.7). Then Pr [ X < 0] = 0 Pr [ X ≤ 0] = 0.00243 Pr [ X ≤ 1] = 0.03078 Pr [ X ≤ 2] = 0.16308 Pr [ X ≤ 3] = 0.47178 Pr [ X ≤ 4] = 0.83193 Pr [ X ≤ 5] = 1.
