As the question is to find the maximum it should be 70 people as the person having phone is 70% and this is the maxim possiblty of having all these things.

Hi ,This is the approach, p(M)=85/100p(M' )=1-(85/100)=15/100similarlyp(P' )=30/100p(c' )=25/100p(h')=20/100no of persons who dosent have all the four =15/100+30/100+25/100+20/100 =90/100percent who speaks all the four = 1- (90/100) =10/100 so answer is 10 %
