There are three independent events with probabilities of 1/3, 2/7, and 1/5. Find the probability that: Exactly one event will happen.
+23246 The probability that the first occurs, the second doesn't and the third doesn't: (1/3)(5/7)(4/5)
or
the probability that the first doesn't occur, the second does and the third doesn't: (2/3)(2/7)(4/5)
or
the probability that the first doesn't occur, the second doesn't and the third does: (2/3)(5/7)(1/5)
Find each of the above individual probabilities and add their answers together.
