Your point being?

1/2*(1+49/99) = 1/2*(99/99 +49/99) = 1/2*(148/99) = 148/198

= 74/99 = 0.747474...

why dont ya just throw the 50 red marbles in one jar, the 50 blue in the other. lable both jars and you should be able to get yourselfs a 100% score.... (without labeling you will know which is which after your first pick)
