Tentukan
A)Kejadian Muncul Mata Dadu Berjumlah 5
B)Kejadian Muncul Mata Dadu Berjumlah 10
C)Peluang Muncul Mata Dadu Berjumlah Kurang Dari 6
D)Peluang Muncul Mata Dadu Berjumlah Lebih Dari 8​

Answer 1

A) Mata dadu berjumlah 5

n(S) = 36

n(A) = (1,4), (2,3), (3,2), (4,1) = 4

P(A) = n(A)/n(S) = 4/36 = 1/9

B) Mata dadu berjumlah 10

n(S) = 36

n(A) = (4,6), (5,5), (6,4) = 3

P(A) = n(A)/n(S) = 3/36 = 1/12

C) Mata dadu berjumlah < 6

n(S) = 36

n(A) = (1,1), (1,2),(1,3),(1,4), (2,1),(2,2),(2,3), (3,1),(3,2), (4,1) = 10

P(A) = n(A)/n(S) = 10/36 = 5/18

D) Mata dadu berjumlah > 8

n(S) = 36

n(A) = (3,6), (4,5),(4,6), (5,4),(5,5),(5,6), (6,3),(6,4),(6,5),(6,6) = 10

P(A) = n(A)/n(S) = 10/36 = 5/18
