Use a calculator to compute the following

Question

In the binomial probability distribution, let the number of trials be n=4, and let the probability of success be p=0.2851

Answer 1

to compute a binomial probability you would need an additional term beyond the sample size (n) and probability (p) ... did it give you any information about the number of successes (x) that it was expecting you to test for? :)

Trials: 4

p = .2851

x= 0,1, 2, 3, 4 You need to choose one of them.

P(x=0) ~~ .2612

P(x=1) ~~ .4167

P(x=2) = .24925 ~~ .2493

P(x=3) = .066266 ~~ .0663

P(x=4) ~~ .0066
