Unlike the other entries in this series, this isn't a collection of little darndest things; it's one big, amazing darndest thing.

The set-up: my grade 8s did a project on probability. The first part was some pretty plain mathy stuff, but part 2 involved researching something in real-life in which probability is useful. This actually wasn't very well done, including the one I'm going to relate to you; most kids just made something up that is completely unrealistic. It was mostly my fault for not giving detailed examples of what I was looking for, though.

Anyway, here is one full response:

Keith is totally in love with Annie Jane, and they have been dating since they met four years ago. They both think they make a great couple, but Julien, Keiths best friends thinks they are not meant for each other. So Keith is gonna have two blind dates to see wether he stays with Annie Jane or with one of the new girls Julien have selected for him.

If Keith feels bad, imagine how Annie Jane is gonna feel while she stays at home waiting for Keith to come back from his blind dates.

At the end, he needs to choose who he wants to keep seing his girlfriend of four years or the new girl, Julien have selected for him.

The probability that Keith selects or chooses Annie Jane is

97/100

and that he selects one of the others is

1/100 1/100

and that he stays alone is

1/100

because he is totally in love with Annie Jane and he doesn't even know the other girls.

Brilliant.
