a number , x is chosen at random from the set of positive integers less than 10 . what is the probability that ( 7 / x ) > x ?
"number x has to be chosen from numbers 1 - 9 ( 7 / x ) > x = > 7 > x ^ 2 = > x ^ 2 - 7 < 0 x can have 2 values only 1 , 2 therefore , probability = 2 / 9 answer e"
divide(subtract(10, 7), 7)
