a number , x is chosen at random from the set of positive integers less than 12 . what is the probability that ( 9 / x ) > x ?
"number x has to be chosen from numbers 1 - 11 ( 9 / x ) > x = > 9 > x ^ 2 = > x ^ 2 - 9 < 0 x can have 2 values only 1 , 2 therefore , probability = 2 / 11 answer c"
divide(subtract(12, 9), 9)
