Probabilities If you attempt to guess 1 number chosen from 49 lottery balls
then the
probability that you are correct is 1/49.
If you have a second attempt, and the
previous ball is not
replaced, then the probability is 1/48.
If you choose 6 numbers then the probability that one of them
is the same as the
first ball drawn is 6/49.
Given that the first number is chosen correctly then the
probability for drawing the second number correctly is 5/48.
The probability of choosing all six numbers correctly is:
6/49 x 5/48 x 4/47 x 3/46 x 2/45 x 1/44 = 1/13,983,816
Which is 13,983,815 to 1
If you have one attempt per day then you could expect to win,
on average,
once during the next 38,285 years!
