The odds of winning the raffle are 1:7; this means that every 8 tickets is a winning ticket and 7 out of 8 tickets are losing tickets.

The probability of winning the lottery can be calculated as the quotient between the number of favorable outcomes and the total number of outcomes:

Let "W" represent the event of winning the lottery:

$P(W)=\frac{nº\text{favorable outcomes}}{total\text{ outcomes}}$

Considering that 1 out of 8 tickets is expected to be a winning ticket, then the number of favorable outcomes is 1 and the total outcomes is 8, then the probability can be calculated as:

$P(W)=(1)/(8)\approx0.125$

The probability of winning the lottery is 0.125 or expressed as a percentage, 12.5%
