WebSep 23, 2014 · 1 Answer Sorted by: 1 If you want at least 1, you could just calculate the probability of having none and take the difference to 1: 1-dbinom (0,12,.2) I guess you could think about it, since it is hinted in the second part of the problem. However, in R the function pbinom gives the cumulative probability; so the expression: pbinom (2,12,.2) WebDetails. The beta-binomial distribution is a binomial distribution whose probability of success is not a constant but it is generated from a beta distribution with parameters shape1 and shape2.Note that the mean of this beta distribution is mu = shape1/(shape1+shape2), which therefore is the mean or the probability of success..
