What values can the cards possibly have? The integers from 1 to 13? Are the values equally likely?

comment Teaching the Concept of Infinity to Children.
Of course, I'm limiting the discussion to real numbers only (and not, say, the extended real numbers). By teaching infinity as the point farthest to the right on the number line, the child should see that questions such as "What is infinity plus one?" are meaningless, because "by definition," there is no number greater than (no point to the right of) infinity.

By the way, in the future, you might want to ask questions like this at Mathematics Educators Stack Exchange.

+1 This is an extremely good answer. I wish more people on this site would answer like this.

I'm sorry if I offended you. Next time, please indicate in the original post the explicit reference to the contest (as you just did now in a comment) so that future readers will be more likely to help you.

Is the math contest this problem was taken from already finished? Or is it still on-going?
