1. PROBABILIDAD DE UN EVENTO
1. P (E1)'
= 1- P (E1)
=0.72
=72%
2.E3'= {e,f,g}
(E2 U E3') = {b,c,d,e,f,g}
E1'= {b,c,d,f,g
A= E1' ∩[E2 U E3'] = {b,d,f,g}
P (A) = 5/7= 0.71 = 71%
3. E4 ∩E3' = {e,f,g}
P (E4 ∩E3') = 3/7 =0.42 = 42%
P (E4 ∩E3') = 0.58= 58%
4. E3 ∩E2= {b,c,d}
E2 U (E3 ∩E2) = {b,c,d,f,g}
B= P (E2 U (E3 ∩ E2)) = 5/7= 0.71 = 71%
