No, the probability of winning the lotto with one line are 42C6,
42!/(6!36!), which is nearly 3 orders of magnitude smaller(5.25 million to
1). The Lotto's argument has always been that since people buy at least
two lines, their odds of winning on a 1.50 ticket are doubled, making it a
2.625 million to 1 shot. Still about as much chance of a pin dropped into
a vat of rice sticking in your grain...but hey.
