This ticket filter accepts or reject randomly selected tickets in the Package. The filter opens from menu Package - Reduce - Random Selection.
You can use this filter as the last step of your lottery strategy when the amount of tickets left in the Package is too large for your betting budget. You can consider this filter as optimized 'quick pick' as it will select a few tickets at random. But the tickets in the Package already passed all your lottery strategy filters so you should have much larger chance of winning than choosing a totally random quick pick at lottery agent's shop. An alternate filter is Systematic Selection or Best Tickets filter.
