Probability equals successful outcomes (7) divided by total outcomes (50).
Therefore the probability that person has a ticket drawn (1 drawing) is 7/50 or 14%

You know that the person bought 7 tickets and there were a total of 50 tickets. All you have to do is put the 7 in the numerator and 50 in the denomonator. So you get 7/50, which is also 14%

50 tickets = 100% (all available)
7 tickets = ?
Use rule of three:
To know how many % 1 ticket has, divide 100%/50=2%.
Than, multiply this by seven (because you want to know what is the probability of seven tickets!) 2%*7=14%
So, the solution is 14%. That's the way you can always use. Only in this case, you can say that 50 is the half of 100, so 7 must be the half of your solution: 14.

P(x) = Favorable Outcomes/Total Outcomes
So,
P(win) = 7/50
