thank you so much i couldnt understand it!!

Answer 4

suppose i had two cards, M and A. What is the probability that you would choose M?

Answer 5

P(X1 = M) = 2/11
P(X2 = M) = 2/11
P(X1 = M AND X2 = M) = P(X1 = M given that X2 = M) . P(X2=M) = 2/11 . 2/11 (since the probabilities don't depend on each other).
P(X1 = M AND X2 = M) = 4/121
