For that to happen, we need to win the first Saturday, but only the second time, therefore the probability is the product of both events No*Yes:
P=(1-1/20)*1/20 = 0.95*.05 = 0.00475. Hope it helps and it is clear for the future!

So the probability of losing is = 1 - 0.05 = 0.95.

Given that we will play each saturday until we win.

So if we win on the second ticket, that means we lost on the first ticket.
