Hi Chris and Tim,
Since 4.1 version, some questions in my questions bank don't work anymore because distrib module seem to be not loaded in Stack. However, it's OK when I try to use some distrib functions in Maxima's command line.
For example the function cdf_normal :
**** Variable question *****
ecartype:rand([2,3,4,5,6]);
moy:rand(20);
bornesup:moy+2*ecartype*(rand(2.0)-1);
bornesup:round(bornesup/0.1)*0.1;
/* solution:round(cdf_normal(bornesup,moy,ecartype)/0.0001)*0.0001; */
solution:cdf_normal(bornesup,moy,ecartype);
**** Question text ****
Let N({@moy@} ; {@ecartype@}).
Compute \[P(X \leq {@bornesup@})\]
******
In this question, Stack returns no result for the solution.
