Ans:0.3
let E be the event that the emp may female or male supervisors...
30% are supervisors.
60% of 30% supervisors=18%male supervisors.
therefore,12% are female supervisors.
The prob(E)=no.of fav chances/no.of total chances.
=>prob(male)+prob(female)
=>18/100+12/100 since,total empoyees in the company are 100.
=>0.3 (probability lies between 0 and 1).
