dbinom(x, n, p) pbinom(q, n, p) qbinom(prob, n, p) rbinom(nobs, n, p)
x,q
| vector of quantiles. |
prob
| vector of probabilities. |
nobs
| number of observations to generate. |
n
| number of trials. |
p
| probability of success on each trial. |
n
and p
. dbinom
gives the density,
pbinom
gives the distribution function qbinom
gives
the quantile function and rbinom
generates random deviates.
The binomial distribution has density
p(x) = Choose(n,x) p^x (1-p)^(n-x)
for x = 0, ..., n.# Compute P(45 < X < 55) for X Binomial(100,0.5) sum(dbinom(46:54, 100, 0.5))
