Question 181742
Sydney couldn't decide ehat kind of ribbon to buy for her hair. 
There was a bin in the store that had 120 ribbons in it.There were an equal number of red,blue,pink,lavender,and white ribbons in the bin.
 One fifth of the ribbons were lacy; the rest were plain. If Syndey closes her eyes nd pulls out a ribbon, what are the odds it will be plain pink?
----------------------
You didn't say whether "plain" excludes lacy.
-------------
1/5 th of theribbons are pink

Odds are (1/5)/(4/5) = 1:4
