    There are 2 drawings, in the 1st one we have to select correct four numbers between 1 and 62 while the 2nd one is to select the one single number between 1 and 16.

    In the 1st drawing, the probability of success is 1 divided by the total number of 4 combinations that can be created from 62 numbers.

    P1 = 1 / 62C4

    P1 = 1 / 557,845

    In the 2nd drawing, the probability of success is 1 divided by 16:

    P2 = 1 / 16

    Since the two drawings must be satisfied before you can win the jackpot, then multiply the two:

    P = P1 * P2

    P = (1 / 557,845) (1 / 16)

    P = 1 / 8,925,520 = 1.12 x 10^-7 = 1.12 x 10^-5 %

    Therefore the odd in winning this lottery is 1 in 8,925,520 chances.
