    A card is drawn from a pack of cards number from 1 to 90
    So
    1) two digits number between 1 to 90 are
    10,11,12,13,…………89
    So there are total 81 numbers between 1 to 90
    Probability =81/90
    =4.26
    2) perfect square number
    So perfect square between 1 to 90 are
    1 ;4;9;16;25;36;49;64;81
    So probability =9/90
    =0.1
    I hope this helps
