Question

solve it quickly it's urgent.

Answer 1

Answer:

It is in the picture!

Step-by-step explanation:

Since we do not have any information I considered you wanted a kind of a general answer.

So we start by changing the probability of the complementary of A and B to probability of A and B. When we have two signals of negation above the letter A and B it means that it is positive, then we just need to remove them.

Continuing the calculations we can get to a solution which is much more simpler than the initial one.

I hope you understand my letter, anything you do not understand please feel free to ask me!
