Let the total probability be 1
Probability that Brian wins a raffle = n/n+2
Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle
Probability that Brian does not win a raffle = 1 - (n/n+2)
Probability that Brian does not win a raffle = 
Probability that Brian does not win a raffle =
Hence required fraction is
Answer:
Negative 6) (4) + (negative 6) (two-thirds)
(Negative 6) (4) times (negative 6) (two-thirds)
(Negative 6 + 4) + (Negative 6 + two-thirds)
(Negative 6 + 4) times (negative 6 + two-thirds)
