Calculate Binomial Tail Probabilities

binomprob calculates the probability of the number of success of interest using a binomial distribution and plots the distribution.

Usage

iscambinomprob(k, n, prob, lower.tail, verbose = TRUE)

Arguments

k

number of successes of interest.

n

number of trials.

prob

success probability. Numeric between 0 & 1.

lower.tail

Boolean for finding the probability above (FALSE) or below (TRUE) the inputted value (inclusive)

verbose

Logical, defaults to TRUE. Set to FALSE to suppress messages

Value

The probability of the binomial distribution along with a graph of the distribution.

Examples

iscambinomprob(k = 5, n = 20, prob = 0.4, lower.tail = TRUE)

#> Probability 5 and below = 0.125599 
#> [1] 0.125599
iscambinomprob(k = 15, n = 30, prob = 0.3, lower.tail = FALSE)

#> Probability 15 and above = 0.01693731 
#> [1] 0.01693731
iscambinomprob(k = 22, n = 25, prob = 0.9, lower.tail = TRUE)

#> Probability 22 and below = 0.4629059 
#> [1] 0.4629059
