The Powerball jackpot increasing each week has generated a lot of excitement, both in the general media and at the school. Jared was so enthusiastic about wanting to share his knowledge on the statistics of lottery wins, so we refreshed our memory on probabilities. We started to work out the odds of winning the jackpot based on a selection of five white balls out of 69 and one red ball out of 26. We had quite a few other teachers joining in, and it was great to see Jared confidently discussing various scenarios with several teachers. We stumbled on just one little thing that Jared is going to solve for his homework.
