You can put this solution on YOUR website!
Bill's probability of being promoted=0.25
Jane's probability of being promoted=0.34
-----
You must subtract Bill and Jane's probability of promotion from 1 to get Doris' probability of being promoted
Doris' probability of being promoted
= 1-0.25-0.34
-----
Doris' probability of being promoted =0.41
