1.3% is 12/890 as a percentage to the nearest tenth
Hello!

The probability of this event is 12/890. To convert that to a percent we will divide 12 by 890 and then multiply by 100 to get our percent.

12/890≈0.01
0.01·100=1%

There is about a 1% chance of the calculator being defective.

I hope this helps!
