Light, The difference between the Major Pentatonic and minor pentatonic intervals listed above, is where the the Major pentatonic (1-3-4-5-6) has a semitone (3-4) listed. Pentatonic formulas have no semitones in them.
Major Pentatonic = 1-2-3-5-6
minor pentatonic = 1-b3-4-5-b7

Major pentatonic scales contain no 4th or 7th interval
minor pentatonic scales contain no 2nd or 6th interval
Hope that helps........
