Can anyone explain the thought process and answer behind this: Sue bought 2 raffle tickets for a fundraiser. 3 tickets are drawn out of 100 for 3 different prizes. What is the probability of Sue winning exactly 1 prize?

3 of the tickets drawn out will win prizes, so the 1 raffle ticket that sue has will need to be apart of the 97 and 1 raffle ticket will need to be apart of the 3. ofc u have to factor in position drawn and order drawn.

Draw out a probability tree, and add the outcomes where there is one win
