Write the reciprocal of the second fraction. First, make sure the y term is on the left side of the equation. Watch the video for a Module before or after (but not instead of) reading the Module in MindEdge. Though it is not written, there is essentially an invisible 1 in front of any variable without a numerical coefficient. Multiply the denominators. Lurking variables may not be included in the study, but affect the variables that were included. Sum of all probabilites = 1.
