  1. I've changed the amounts won by the winners to make it a bit easier (in a way). The original one proved to be too tough! Humble apologies to those who have spent their valuable time by working on the previous OP. The revised OP now reads as follows: In a recent Lotto draw, Jeremiah won $790, Philemon $1650, and Ridgeley $464. How much did Waltraud and Xhuliana win in the same draw?
  2. Suppose there is an international football (soccer) team consisting of 20 players and selected as follows from five countries: Two players from Spain Three from Italy Four from France Five from Brazil Six from Germany The squad only includes one goalkeeper, who plays for an Italian club, whereas the captain plays for a French club. Assuming the goalkeeper and the captain are included in every selection of eleven players, how many different teams could be selected from the twenty players (irrespective of position) if at least three German club players are included in each selection?
  3. Answer will only appear after a few people have had a go at and possibly have solved it!
  4. In a recent Lotto draw, Jeremiah won $1138, Philemon $634, and Ridgeley $205. How much did Waltraud and Xhuliana win in that draw? Edit: Jeremiah won $790, Philemon $1650, and Ridgeley $464
  5. Excluding straight lines, impossible triangles and non-isosceles triangles, the distribution of all isosceles triangles is as follows ...

  9. It's a regular pentagon, Oumaima!
  10. First placed in 2007 ... "Best answer" indicated, but not visible!
  11. I thought that, if anyone who still wants to know the answer, it follows below ... Clues by those who knew the answer (or have learned it) were starting to show up all over the place (remorse, S & O, transmitted, Message In A Bottle lyrics at end of verse (SOS repeated) and title of ABBA song (SOS). For people that are still battling with their brain, the characters come from the International Morse Code in ascending order of "dots" or "dashes" Thus ... "SOS" = Originally, SOS did not actually stand for anything (e.g. "Save Our Souls"). It was used since the letters S and O are easy to make and are distinctive.
  12. ... and as the title of one of ABBA's songs too!
  13. Perhaps you've seen this one before, but I've added an extra twist to it! What are the next two entries in this sequence? All credit due to the original designer from whom I've borrowed it (source to be disclosed once question is answered).
