CPE = 1/3 CPB = 1/3 CPA=1/4 CAE=1/8 ABC

BND=1/2 BNA=1/6 BNC=1/7 BCD=1/14ABC

AMF=1/4 AMC=1/8 ABM= 1/9 ABF=1/36 ABC

AMND=ABF – BND – AMF

=1/4 ABC = 1/14 ABC = 1/36 ABC= 7/42 ABC

BEPD= BCD = CPE

= ½ ABC – 1/8 ABC = 3/8 ABC

MNP = ABC – AEC – BEPD – AMND

= ABC – 1/3 ABC – 3/8 ABC – 7/42 ABC

= 1/8 ABC
