I was hoping someone would be able to tell me whether I diagrammed the following conditional statements correctly:

1.) If both A and B come, C will also come

2.) If X comes, neither Y nor Z will come.

My attempted diagrams:
1.
A and B ---> C
CP: Not C ---> Not A AND B

2.
X ---> Neither Y and/or Z
CP: Y and/or Z ----> Not X

[moopness]

A + B -> C
-C -> -A/-B

X -> -Y + -Z
Y/Z -> -X

Thanks....I appreciate it

1.) If both A and B come, C will also come

A & B --> C
~C --> ~A OR ~B (or both)

2.) If X comes, neither Y nor Z will come.

X --> ~Y & ~Z [this can be written X --> ~Y and X --> ~Z]
Y OR Z (or both) --> ~X [this can be written Y --> ~X and Z --> ~X]
