The probability of winning raffle ticket is 15%. If you bought 40 tickets, how many winning tickets should you expect to have?

Answer 1

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%.
