The tree diagram represents an experiment consisting of two trials.
P(A and C) is 0.2
The tree diagram represents an experiment consisting of two trials
P(A) = 0.5
P(C) = P(A/C) P(A)
P(C) = (4/10)x 0.5 = 0.2
P(A ∩ C ) = P(A) + P(C) - P(A ∪ C)
P(A ∩ C ) = 0.5 + 0.2 - 0.5
P(A ∩ C ) = 0.2
Therefore, the tree diagram represents an experiment consisting of two trials P(A and C) is 0.2
