BrainBashers Puzzles

You are given 50 white marbles and 50 black marbles along with two jars.

You are asked to place all 100 marbles into the jars in any way you choose.

Afterwards, you will be blindfolded, the jars will be shaken and rearranged, and you will be asked to select just one marble (from either jar).

How would you arrange the marbles originally to maximise the probability of drawing a white marble?
