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)?

Please walk me through this. Thanks.

Hi BarandaMan;

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

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.

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!

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.

I would think it is a typo.
