Resposta:
A) o número ímpar.
B) [tex]\frac{9}{29}[/tex]
C) [tex]\frac{2}{29}[/tex]
D) [tex]\frac{5}{29}[/tex]
E) [tex]\frac{24}{29}[/tex]
Explicação passo a passo:
A) De um universo de 29 alunos, 15 serão numerados com valor ímpar e 14 com valor par; portanto, há mais possibilidades favoráveis de se escolher um número ímpar.
[tex]A_{total}[/tex] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29}
[tex]A_{imp}[/tex] = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
[tex]A_{par}[/tex] = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}
B) [tex]A_{mtpl3}[/tex] = {3, 6, 9, 12, 15, 18, 21, 24, 27}
C) [tex]A_{mtpl10}[/tex] = {10, 20}
D) [tex]A_{mtpl5}[/tex] = {5, 10, 15, 20, 25}
E) [tex]A_{n-mtpl5}[/tex] = {1, 2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14, 16, 17, 18, 19, 21, 22, 23, 24, 26, 27, 28, 29}
