I'm trying to figure out how to represent 100 people where each one has a 30% probablity of getting sick.

I think sample can be used but not I'm exactly sure how to achieve that. Basically how many people are sick?

When I type this into Maple

(i mod 3)*(i mod 4)

Maple gives the answer i^2

That doesn't seem right to me.  Is that a bug?

Simple, but racking my brains, what is the formula for the sequence 2,3,4,6,8,9,10,12,14,15,16,18,...?

How could this be set up in Maplesim?  A vibration signal is imparted on the box and we want to observe the behavior of the sprung object inside the box.

How can I do a color inversion on a jpg image in Maple?
