Compute the indicated probabilities by referring to the probability tree.(A) P(M∩S)(B) P(R)A probability tree diagram has a root that splits into two branches labeled M and N, with probabilities 0.9 and 0.1, respectively. Branch M has two secondary branches labeled R and S, with probabilities 0.1 and 0.9, respectively. Branch N has two secondary branches labeled R and S, with probabilities 0.3 and 0.7, respectively.(A) P(M∩S) = nothing(Type an integer or a decimal.)
