Independent or dependent

A coin is tossed 4 times A: getting all heads B: all tails. Are independent or dependent.

These will be dependent because the next flip depends on the flip before.

P(A and B) doesn't equal P(A)P(B)

Would P(A and B)= 1/8?

I am having trouble with the formula I do not know what to say for P( A and B)
P(A)= 1/16
P(B)= 1/16

Thanks

Since A and B are mutually exclusive P(A and B)=0 (they cannot both simultaneously occur)
