Probabilities With Socks

For the last couple of weeks at strand we have been working on Statistics. Also probability, and that's what I will be informing you on today.
We tested this by reaching into a paper bag and pulling out socks. In the bag was 2 purple socks and 2 blue socks. We pulled out 2 socks and saw if they were odd or a pair. We did this theory lots of times to see what our final answer was. We found out it was 50% chance to get a pair and 50% to get odd.
After doing this we added in another purple sock, then we tried to find the percentage. To find out this answer we did a graph. This was my graph:
We found out that 6/25 was the answer to getting an even pair of socks. Also 6/25 was the answer of getting an odd pair of socks. This means there is a 12/25 possibilities of getting a odd or even pair of socks. This is a screencastify of myself explaining this in more detail:
