    Looks like some sort of a bug in the school's system. This happens a lot in Aventa or Accelerate classes. Screenshot and email your teacher or mentor, if you have them.

    I'm just a 9th grader, but I don't think it makes sense at all and is a mistake. What school system is that?

    What's the probability that Gary's name will be drawn on the first draw?

    When people say 50,50 they means there is a 50% chance of one event happening and 50% chance of the other event happening.

    He had 10 out of 50 percent chance each time they drew the tickets.

    1/5 times 1/5 equals .04 or 4%. You multiply the number by itself each time you draw again without taking out the tickets.

    By taking out tickets I mean taking them out without putting them back in.

    The probability of an event happening is: \(p(even) = \dfrac{number ~of~desired~outcomes}{total~number~of~outcomes} \) There are 10 tickets that belong to Gary. There are a total of 50 tickets. Any ticket that belongs to Gary is a desired outcome. The number of desired outcomes is 10. There are 50 possible outcomes since there are a total of 50 tickets. For the first drawing, the probability of taking out a ticket with Gary's name is: \(p(drawing~ticket~with~Garry's ~name) = \dfrac{10}{50} = \dfrac{1}{5} \) Then the ticket is placed back in the bag, and a new drawing takes place. Since all tickets are in the bag, the second drawing is exactly the same as the first drawing, so we have: \(p(drawing~ticket~with~Garry's ~name) = \dfrac{10}{50} = \dfrac{1}{5} \) The probability of drawing Gary's name two times in a row is the product of the individual probabilities: \(p(drawing~Gary's~name ~followed ~by ~drawing~Gary's ~name) = \dfrac{1}{5} \times \dfrac{1}{5} = \dfrac{1}{25}\) Now we need to covert 1/25 to a percent. First, we convert 1/25 to a decimal by dividing 1 by 25. 1/25 = 0.04 We get 0.04 Then to convert a decimal to a percent, we multiply by 100 (move the decimal point two place to the right) 0.04 + 100 = 4 Answer is 4%
