This answer is FALSE the question reads AND which means that all must be correct. OR would mean any 1 item is sufficient

Hi Steven,

When we use OR(||) we are saying if side 1 is true OR side 2 is true then return true. Also long as one side is true it will return true. Example:

true || true will return true
true || false will return true
false || true will return true 

When we use AND(&&) we are saying both sides must be true. Example:

false && true will return false
true && true will return true

But there are exceptions to this for example:

!false && false would return true
!false && true would return true
!true && true would return false

This is done using the NOT(!) operator

The correct answer for your related question is true It says assuming your count is set to 90 what is stored:

boolean answer = (count > 30 && count < 120); 

substitute count for 90 (90 > 30) && (90 < 120) 90 is greater than 30 && 90 is less than 120. Both of which are true

Hope this helps a little Michael :)
