This has probably been done before but here are my item results from opening 151 lockers.
Blue: 223
Purple: 126
Pink: 61
Red: 38
Yellow: 5
So, when opening a locker, the percentage chance of getting a particular color item is:
- Blue: 49.23%
- Purple: 27.81%
- Pink: 13.47%
- Red: 8.39%
- Yellow: 1.10%
At the end of the day, I was refunded so many duplicate points I ended up opening around 500 lockers. It takes eight seconds to open a locker and two seconds to buy one. So, it should have taken me about 83 minutes, but it was more like two hours as I watched youtube and did other things.
Below is the lowlight of my opening session as I chase after this elusive mask.
