two CASES:-

1) when E is there
M will not be there
now two subcases
a) with P
choose 2 out of remaining 3 = 3C2=3
b) without P
only three remaining and all three are to be chosen = 3C3=1

2) when M is there
E and therefore P cannot be there..
Only 3 remaining and all 3 are to be chosen = 1

total \(3+1+1=5\)
C

Total ways to make a team - 6C4 = 15
Unwanted 1 Scenario (where E&M are together) - 4C2 = 6
Unwanted 2 Scenario (where either of P or E are on team) - 4C3 = 4

Desired = 15-6-4 = 5

Hope this helps!

Edward In, Miller Out, Paul Out:
total combo = 1 * 3c3 = 1

Paul In, Edward MUST be in, Miller Out:
total combo = 3c2 = 3

No Edward, so No Paul, Miller In:
total combo = 3c3 = 1

total = 5
