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

Hi Tia,

You didn’t specify the desired number of successes, but the command for this in TI-83 or 84:

2nd-VARS-binompdf (n, p, x)

n= total sample size = 4

p= probability of success = 0.2851

x= desired number of successes

I hope this helps.

Answer 2

Ti-84 plus:

Cliack 2nd -> VARS (Dist)

A. Binomial PDF

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
