Re: If x is to be selected at random from T, what is the probabi

Solving the equation for x : 1/4x – 5 <= 0

(x – 20)/4 <= 0

x – 20 <=0

x <= 20,hence the question can be reframed as,what is the probability that x <= 20?


Stmt 1 : T is a set of 8 integers – here x could be any integer so it could be <20 or = 20 or > 20

Since we can not arrive at a definite answer,this statement is insufficient



Stmt 2 : T is contained in the set of integers from 1 to 25, inclusive

Here again,x could be any integer so it could be <20 or = 20 or > 20

Since we can not arrive at a definite answer,this statement is insufficient



Both : x could be any integer so it could be <20 or = 20 or > 20

Since we can not arrive at a definite answer,both statements are insufficient
