So we can't have
TTT
PPP
SSS
could have
PST --- C(3,1) x C(3,1) x C(5,1) = 4
PPT --- C(3,2) x C(5,1) = 15
PPS --- C(3,2) x C(3,1) = 9
TTP --- C(5,2) x C(3,1) = 30
TTS --- C(5,2) x C(3,1) = 30
SSP --- C(3,2) x C(3,1) = 9
SST --- C(3,2) x C(5,1) = 15
total = 108
108 is not correct. Thanks for trying tho Reiny!
It was a simple typo,
in the first of the listings , it should have been
PST --- C(3,1) x C(3,1) x C(5,1) = 45
changing my total to 153
