The minor pentatonic scale interval pattern is
1 - b3 - 4 - 5 - b7
whereas the major pentatonic scale formula is
1 - 2 - 3 - 5 - 6
They have only two chord tones in common, the tonic (1) and the fifth (5)
major=tonic-whole-whole-whole&half-whole-(and whole&half to tonic)
minor=tonic-whole&half-whole-whole-whole&half-(and whole to tonic)
blues=tonic-whole&half-whole-half-half-whole&half-(and whole to tonic)
