Treasure Hunting Pa

If I play a lottery game with chances of 1:142,500 for each game, and purchase of 5 plays, what are the odds, then?
Is it like 1:65,000 or something or not go for both? I am good at math, but I keep getting confused answers from the people. I know they are stupid though probabilities, but am just curious. I play this game occasionally called Treasure Hunt PA lottery. Thank you!
You will have the same opportunities to win on each ticket on the basis of 'shared win the game. "Otherwise, why not buy specific 142,500 entries each time the boat is more than $ 142,500? It is an acceptable way to donate to the elderly residents I guess – less costs of administration) Dr. mathematics directions http://mathforum.org/dr.math/faq/faq.prob.world.html the combination and permutation will give the definitive answer and a good reason to believe:)
