An event with probability zero cannot occur under the given probability model, defining it as impossible (though in continuous distributions, point events have P=0 but are not impossible).
Explanation:
WPI primarily tracks prices of goods (primary articles, fuel, manufactured products) at wholesale stages, with limited service coverage, making it more responsive to commodity price fluctuations.
Explanation:
P(AB'C) = 1/2 * 1/3 * 3/4 = 3/24; P(AB'C)? Let's compute exactly two: A and B not C: 1/2*2/3*1/4=2/24; A not B C: 1/2*1/3*3/4=3/24; not A B C: 1/2*2/3*3/4=6/24. Sum = 11/24.
