If you play this game you have to make a tally chart and spinning the pin then you started the game. There is a 50 50 chance of you getting green or red. It is fair because these 50 50 chance. Kelvin is the lucky one because his number is 7 and he got red 7 and 13 green. It was even because half is red and half is green. 0.50 and 50% is another way of saying ½. We had to spin the pin 30 times or 20.
