When finding single or multiple probabilities using the binomial distribution on the calculator, which function do I use respectively?
· In a binomial probability question that only asks you for one single probability (e.g. P=48), use binompdf· In a binomial probability question that asks you for multiple probabilities (e.g. P≥48), use binomcdf· In a binomial probability question that asks you for example (P≥48), do 1 – (P<48)· To show your working out on P2, write (n = trials, p = probability)
