If A = {w1,w2.....wn}, where wi are the outcomes, then
P(A)= P(w1)+P(w2) ..... P(wn)
True
Probability of an event is the sum of probabilities of outcomes associated with it. If we throw a die, to find the probability of an even number turns up, we will add the probability of 2, 4 and 6 (outcomes associated with it)
⇒ The given statement is correct.
