\frac{2}{n+2}

Step-by-step explanation:

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 = \frac{n+2-n}{n+2}

Probability that Brian does not win a raffle = \frac{2}{n+2}

Hence required fraction is  \frac{2}{n+2}
