Every month there is prize draw, whats the probability of winning prize draw of 20 customers > Every month there is a prize draw for customers who complete the survey. One customer will win the prize. Last month 20 customers completed the survey. what chance does the customer, Bradley have of winning the prize for last month's? **My attempt** : My answer is $5$, because calculating weeks by $20$ customers, one month there are $4$ weeks and divide that by $20$ customers.

Since there is one draw per month, and Bradly participated in the draw for a single month for which there were $20$ participants in total, the probability that Bradley wins is

$$ 1/20. $$
