To find the probability that a randomly chosen student from the class plays either Basketball or Baseball, we first calculate the number of students who play at least one of the sports using the principle of inclusion-exclusion. The number of students who play basketball or baseball is given by:
[ n(B \cup S) = n(B) + n(S) - n(B \cap S) = 12 + 16 - 5 = 23 ]
Thus, the probability that a randomly selected student plays either basketball or baseball is:
[ P(B \cup S) = \frac{n(B \cup S)}{n(T)} = \frac{23}{27} ]
Therefore, the probability is (\frac{23}{27}).
