Question

1. a. Se P(A ou B) = 1/3, P(B) = 1/4 e P(A e B) = 1/5, determine P(A).

Answer 1

 P(A) = {{},{0},{1},{01}} 
b) P(B) = {{},{1},{3},{5},{1,3},{1,5},{3,5},{1,3,5... 
c) nP(A) = 2^|A| = 2^2 = 4 
d) nP(B) = 2^|B| = 2^3 = 8

Answer 2

Resposta:

Explicação passo-a-passo:

P(A) = {{},{0},{1},{01}}

b) P(B) = {{},{1},{3},{5},{1,3},{1,5},{3,5},{1,3,5...

c) nP(A) = 2^|A| = 2^2 = 4

d) nP(B) = 2^|B| = 2^3 = 8
