Hi everyone,
We have a table so
| Gold | Silver | Rose gold | |
| Necklace | .1 | .19 | .11 |
| Earrings | .07 | .15 | .13 |
| Rings | .06 | .09 | .1 |
Find the probabilty the priece of Jewerly is a gold earring or is a silver ring.
Do I have to add only .07 + .09 or
Do i have to add all the earrings columns + the silver colums ? Without double the .15 ?
If anyone could help me with that probleme that would be nice, thank you !
Enjoy your evening and your weekend! :)
God bless you !
