A number, x is chosen at random from the set of positive integers less than 10. What is the probability that (7/x) > x? Options:
A) 1/5  B) 7/9  C) 1/3  D) 2/3  E) 2/9
Number x has to be chosen from numbers 1-9   (7/x) &gt; x   =&gt; 7 &gt; x^2   =&gt;x^2 - 7 &lt; 0   x can have 2 values only 1 , 2   Therefore , probability = 2 / 9   Answer 2/9
