We know that two digit nos. range from 10 to 99
so,
Total nos. between 10 and 99 = 90
and,
No. of favourable outcomes i.e., Perfect squares ranging in 10-99 = 6
so,
P [Perfect squares] =>
= 6/99
= 2/33
so,
Total nos. between 10 and 99 = 90
and,
No. of favourable outcomes i.e., Perfect squares ranging in 10-99 = 6
so,
P [Perfect squares] =>
= 6/99
= 2/33

why -10 to -99 are not considered
Bro!! This is because there is no such perfect square lying between -10 to -99 as the squares of any integer is never ever negative....☺☺
Hope you got it☺☺ ✌✌ ✅✅ ✔✔

Answer: 86/90
Step-by-step explanation:
total number of numbers from 10 to 99 = 90
because when we subtract 10 from 100 gives 90
no.of perfect squres from 10 to 99 = 16, 25,36,49,64,81
we need the which are not perfect
so,
p( being the number not a perfect square)=90-6
= 86
=
guys!!! hope you all got it....
