Answer 2

        i did my best thank you please thank me*shamelessly*

Answer:i at last and ii  360

Step-by-step explanation:

let P and I denote the percent o chinese tourists who have already visited pakistan and india

n (P)=40%            40 /100 * 1200=480

n(I)=45%              45 /100*1200= 540

n (U) =1200

n (P ∩ I) =15%         15/100*1200  =180  

    ___

n (P ∪ I) = ( suppose X )

                                                          ____

  ii) n( U) =n (P) + n (I ) - n(P ∩ I) + n ( P ∪ I )

or, 1200=480+540-180+X

or,1200=1020-180+x

or,1200=840+x

or,x =1200-840

∴x= 360

So, 360 tourists havenot visited anyu o these two countries.
