Date: Around 1995
What is the probability of winning the Texas lottery by entering once? This
is the state lottery where six numbers between 1 and 50 are chosen.
The number of combinations of 6 items taken from a pool of 50 is:
------ = 15,890,700
Only 1 of these will be the winning combination, so you have 1 chance in 15,890,700 of winning with a single lottery ticket.
Therefore, the probability is 1/15,890,700 or about 0.000000063.
