FAN AND MEDAL
Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals. Maggie keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns over another tile without looking. What is the probability that the second tile that Maggie turns over has a plant on it?

well, there is a high chance since there are 4 more plant tiles (after removing the one she picked out already) then animal tiles
OpenStudy (pandagurl):
