There are 26 tiles in a bag. of these, 15 are purple, and the rest are yellow. what are the odds in favor of drawing a yellow tile?

Try drawing yourself a chart to help you figure it out.  Here is an example:

45

-

15

__

30

This leaves 30 yellow, and 15 purple.  Each letter will be used as five tiles of the color.  

(P,P,P) : (Y,Y,Y,Y,Y,Y)  

This shows the number of tiles, NOT the answer.  Because this is in the favor of the Yellow tiles, and 30 is twice the amount of 15, you will have 30:15.  To simplify this to it's SPF (smallest possible form), you would divide 30/15, which gives you 2:1.  I hope this helps you.  

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
