given n=80 p=0.21 and x=15 find p(x) and round to 3 decimal places. p (X=15) =
Added by Encarnacion G.
Step 1
Step 1: Recall the formula for the probability mass function (PMF) of a binomial distribution: \[ P(X = x) = \binom{n}{x} \cdot p^x \cdot (1-p)^{n-x} \] where \( \binom{n}{x} \) represents the number of ways to choose x successes out of n trials, and \( p^x \cdot Show more…
