For example, binompdf(20,183,5) = .153
My teacher gave us directions which said
- press DIST -> select 0:binompdf -> enter -> fill in n,p,x -> enter
When I get 'binompdf(' on my calculator, I then enter in the data '20,183,5)' and enter, but it says error without giving me any answer. What am I doing wrong?

Solution: I believe you meant binompdf(20,0.183,5)
Explanation: The second argument of the binompdf function (which had a value of 183 in the given problem) is the probability of success, and therefore must be a value between 0 and 1 (inclusive). In order to troubleshoot further, it is necessary to look at the problem, but since binompdf(20,0.183,5) gives the result 0.153 you specified in the problem, I'm assuming you meant 183/1000 for the second argument

The p parameter represents probability of success on a single trial. Probability cannot be greater than one, but you have entered 183.
