In a bag of keys, there are 15 silver keys, 5 black keys, 11 copper keys, and 4 painted keys of various colors. One key is drawn out at random. What is the probability that the key that is drawn is silver or copper?
There is a 74% chance that the key drawn will be silver or copper.
I got this because I added all of them and got a total of 35 and then I took the total of silver and copper keys being, 26 and I divided 26 from 35 and got 74%
