Computer Day

Before heading to the computer lab, we wanted to see how our theoretical probability from our games of Rock, Paper, Scissors games yesterday stood up to the experimental probability we found.  We combined all of the data from the three classes.

We had a total of 1696 games played.  This meant that we SHOULD have had about 565 wins, 565 losses, and 565 ties.  Wow!  It was close!

I also wanted to touch base with the kids on the game Rock, Paper, Scissors, Lizard, Spock.  We walked through the process of listing all possible combinations (watch the video:  Rock, Paper, Scissors, Lizard, Spock). 

 Once we had found that there were 10 wins, 10 losses, and 5 ties, we discussed whether this was a fair game.  Most agreed that it was since you have the same number of losses and wins.  They felt that since a tie doesn't benefit either player, it did not matter that there were fewer chances to get a tie.

We finished out the day in the computer lab working on mathematics using khan academy.
