Los resultados posibles de un experimento aleatorio son A,B,C y D, conprobabilidad de 0.1,0.3,0.5,0.1,

S{ a , b , c , d }
p(a) = 0.1
p(b) = 0.3
p(c) = 0.5
P(d) = 0.1
---------
1.0
Sea A el evento ( a , b )
Sea B el evento ( b , c , d )
Sea C el evento ( d )

Encontrar la probabilidad del evento A , B , C ,
p(A´) , P(B´) , P(C´) , P(A Ω B) , P(A U B) , P(A´Ω B) , P(B U A´). ?

P(A) = P(a) + P(b) = 0.1 + 0.3 = 0.4
P(B) = P(b) + P(c) + P(d) = 0.3 + 0.5 + 0.1 = 0.9
P(d) = p(d) = 0.1
P(A Ω B) = 0.3
P(A U B) = 1
P(A´) = 1- 0.4 = 0.6
P(B´) = 1 - 0.9 = 0.1
P(C´) = 1 - 0.1 = 0.9
P(A´Ω B) = (A´) = c + d , (B) = b , c , d = 0.6
P(B´Ω A) = 0.1
