please make me brainlist

Answer 2

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
