If a player bets $1 on a specic numbered slot, they either win $35 (ie a net gain of $35} if the roulette ball stops in that slot, or lose the bet of $1 if it does not. Assume that each roll of the roulette ball is equally likely to stop in any of the 38 slots. Mason decides to repeatedly make bets of $1 on the roulette wheel. Give exact answers for each question below {do not approximate and always use fractions rather than decimals). (a) What is the probability that Mason wins for the rst time on their 51st bet? @D [b]: What is the probability that Mason wins for the rst time on or after their 68th bet? @D (c) What is the probability that Mason has made a positive net gain of winnings after 56 bets\"? @D {d} If you wanted to estimate the probability that Mason won at least 9 times out of 184 bets as 13(32 2:} (using the continuity correction}, where Z M NH], 1] is the standard normal random variable, the value of a that you should use would be u. ,3 : _ Mb where d = Number , b : Number {Remember to use fractions and never decimals in your answer )
