Answer:
Step-by-step explanation:
TOTAL NUMBER OF BOYS = 15
TOTAL NUMBER OF GIRLS =20
TOTAL NUMBER OF MEN= 30
TOTAL NUMBER OF PROPLE IN GROUP = 70
THEREFORE, 70-(15+20+30)=70-65=5
THAT IMPLIES TOTAL NUMBER OF WOMEN = 5
THEREBY P(SELECTED PERSON IS A WOMEN)=TOTAL NUMBER OF WOMEN / TOTAL NUMBER OF PEOPLE IN THE GROUP= 5/70=1/14
ANSWER=1/14
