Question

soffy and tolly choses 1 random integer between 1 and 10.what is the probablity of neither chosen integer to be the square of the other

Answer 1

squre numbers 1 4 9....
let num chosen be a and b.
if a=1, b not 1. if a=4, b shouldnt be 2.. if a= 3 then b shouldnt be 9.
also vice versa.
total outcomes = 10 * 10 = 100.
unfavorable outcomes = 3 + 3 = 6.
prob = 94/100 = 0.94
