15% of all model X computers require a warranty repair.
It says AT LEAST, so it means main board 50% or battery 20% or BOTH 10%.
Therefore 50% + 20% +10% = 80%
0.15 * 0.80 = 0.12
12% of all model X computers will need to have atleast the main board or battery replaced during the warranty period

During the warranty 15% of ALL model X computers require a repair.
The if statement: What % will need to have the main board OR battery replaced during the warranty period?
50% + 20% = 70%
15/100 = 0.15 * 70 = 10.5%
Therefore 10.5% of all model X computers.
