No. of students own a smart phone=B= 84%
No.of students own a tablet=A
No. of students own a smart phone and tablet= A∩B =38%

We use the conditional probability to do this problem;
                           Pr(A|B)=Pr(A∩B)/Pr(B)
                                       =0.38/0.84
                                       =0.45
                                       =45%(no. of students own a smartphone also own a tablet)
