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? 22.2% 28.6% 65.0% 75.0%

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):

so that eliminates the first 2

the Last one is, as a fraction, 3/4

OpenStudy (anonymous):

OpenStudy (pandagurl):

and the third one is, as a fraction, 13/20

OpenStudy (anonymous):

OpenStudy (pandagurl):
