Exercícios de ProbabilidadeQuestão 1:Dois dados são lançados simultaneamente. Determine a probabilidade de:

S = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6),(6,1), (6,2), (6,3) ,(6,4), (6,5) ,(6,6)} n(s)=36

a) A soma ser menor que 4.A={(1,1) (1,2) (2,1)}n(a)=3P(a)= 3/36 = 1/12 = 8,33%

b) A soma ser 9.B= {(3,6) (5,4) (6,3) (3,6)}n(b)=4P(b)= 4/36 = 1/9 = 11,1%

c) A soma ser menor ou igual a 5.C={ (1,2) (2,1) (1,3) (3,1) (4,1) (1,4) (3,2) (2,3)}n( c) =8 P( c)= 8/36 = 2/9 = 22%

d) O primeiro resultado ser maior que o segundo.D={(2,1) (3,1) (3,2) (4,1) (4,2) (4,3) (5,1) (5,2) (5,3) (5,4) (6,1) (6,2) (6,3) (6,4) (6,5)}n(d)=15P(d)= 15/36 =5/15= 41,66%
