0.043% aka 1:2267
Pretty easy to calculate.
Your number of tickets: 135
Total number of tickets this week: 4,591,142
Number of winners: 15
To then find chance per ticket, just divide number of tickets in total with number of winners: 4591142 / 15 = 306,076
The win chance per ticket is 1:306,076.13
You got 135 tickets.
Divide win chance per ticket with your number of tickets:
306,076.13/135=2,267
Your win chance with 135 tickets is therefore 1:2267. You need to have 135 tickets in 2267 weeks in a row to be able to say you're "due" a win😉
This equals 0.043%
Edit: just realised you had 132 tickets, not 135. So it's actually lower than I calculated. I cant be bothered to recaulcate it from 135 tickets to 132
