I did the question from a book, and in the back ith as the answers. The first line of my original post shows what the answer is in the textbook. It must be wrong, I will write a letter. It is simple inequality I thought... must be printing error.

Hey!
That is exactly what I got! Thank you. That is why I am confused, because the 3pq I posted it in the ANSWER BOOK. Which is why I am confused by this!
It cannot be the answer from the inequality!

Hi;
Subtract 6pq from both sides.
Divide both sides by 3.
Divide both sides by (1-p)(1-q) provided that p,q are both less than 1.
I do not know where the 3 comes from in your question.

Yes I do! That is what the answer says but i do not understand how it gets past the 'implies' after rearranging

Hi BarandaMan;
Do you mean

9pq < 6pq +6(1-p)(1-q). Implying that 3pq/(1-p)(1-q) < (less than or equal to) 2
PLEASE explain this somebody! I don't understand how this works? Does it not equal 3<6(1-p)(1-q)?
