How to Use The Probability Calculator:

*	You must enter the probability of two events (A and B) in the appropriate fields.
*	The probabilities of the two events MUST be in fraction format.
*	The probability of event A must be typed in the two pink text fields on the left side (with the numerator on the top text field and the denominator on the bottom text field).
*	The probability of event B must be typed in the two pink text fields on the right side (with the numerator on the top text field and the denominator on the bottom text field).
*	All four digits entered must be integers.
*	Press the P(A and B) button to find the probability of event A and event B both happening.
*	Press the P(A or B) button to find the probability of either event A or event B happening.
*	Press the Reset button to clear all fields.
*	If the two events are Mutually Exclusive (disjoint) then the "ME (disjoint)" radio button should be turned on.
*	If the two events are NOT Mutually Exclusive (joint) then the "NME (joint)" radio button should be turned on.
*	The two blue boxes on the bottom represent the result in fraction format. (the upper blue box is the numerator of the result, and the bottom blue box is the denominator)
*	When the "and" or the "or" buttons are pressed, the resulting fraction will be displayed in the result text fields depending on the button you press.
*	If either one of the probabilities is greater than 1 and you press the "and" or the "or" button the result text field will display "> 1".
*	If ANY of the four digits entered by the user (the numerator and the denominator of the two fractions) is smaller than 1, the result box will display a error message stating which text field is smaller than one.
*	If the two events are Mutually Exclusive (with the ME button selected), then the sum of their probability should NOT exceed one. If it does then that means they are NOT Mutually Exclusive and the result text fields will display "*MEX*". In this case just select the NME radio button and ask for a new result.
