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?

Step-by-step explanation:

We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .

Number of tiles with picture of plants =7

Number of tiles with picture of animals =2

Total number of tiles =7+2=9

We have to find the probability that the second tile that Maggie turns over has  plant on it .

When she removes one tile of picture of plant then she has number of tiles of picture of plants =6

Total number of tiles =8

Probability,P(E)=

Using the formula then we get

The probability that she finds tile of picture of plant =

part a: 1.08

part b: 27.59
