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?
15 silver keys, 5 black keys, 11 copper keys, 4 painted 35 total 15 + 11 = 26 26/35 = 0.7428 ≈ 74.28% probability
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%
