The expected number of winning tickets can be calculated by multiplying the total number of tickets by the probability of winning:
Expected number of winning tickets = 40 tickets x 0.15 = 6 tickets
Therefore, you should expect to have 6 winning tickets if you bought 40 tickets and the probability of winning is 15%.
