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 at random.

What is the probability that the key drawn is silver or copper?

Answer (3)

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%

The probability of drawing a silver or copper key from the bag is approximately 74.28%. This is calculated by determining the total number of keys and the number of favorable outcomes. Specifically, there are 26 silver and copper keys out of 35 total keys.
