If a number is chosen at random from the set (negative 10 comma negative 5 comma 0 comma 5 comma 10) , what is the probability that it is a member of the solution set of both (3 times x) minus 2 less than 10 and x + 2 greater than negative 8 ?

Hint

You can solve the system of inequalities for , or you can check each of the five elements of the set to see whether or not it is in the solution set of both inequalities.

Answer

If (3 times x) minus 2 less than 10 and x + 2 greater than minus 8 , then negative 10 less than x less than 4 . The numbers from the listed set that satisfy these inequalities are negative 5 and . There are five elements in the listed set, so the probability of a number chosen at random from the set being a member of the solution set of both inequalities is 2 over 5 .
