The answer: 1 in 200 keyboards have sticky keys
Here's how you know:
If 99.5% of keyboards DO NOT have keys that stick, then 0.5% of keyboards DO have keys that stick
1% is 1 in 100, and 0.5% is half of one percent, so it's 1 in 200!
What is number sense?
One of the goals of CSM is to build your number sense -- a deep sense of how numbers fit together, and what they really mean. In the problem above, for example, it's easy to think of 99.5% as almost all -- but that's not very helpful. And if you think of 99.5% and 99.995% both as almost all, you wouldn't see that the first is 1 in 200 and the second is 1 in 20,000!
With CSM, you'll learn to see numbers in a different, more confident way.
Take the CSM Course to learn how to do problems like this and build your High Performance skills (like persistence, self-reliance, and problem-solving).
When you complete the CSM Course, you'll earn your CSM Certificate to show employers that you have what it takes!
