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)

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)

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
