Perhatikan tabel distribusi frekuensi variabel acak berikut! x 1 2 3 4 5 6 P(X = x) 1/24 1/8 1/6 k 1/3 1/12
Perhatikan tabel distribusi frekuensi variabel acak berikut!
x | 1 | 2 | 3 | 4 | 5 | 6 |
P(X = x) | 1/24 | 1/8 | 1/6 | k | 1/3 | 1/12 |
Nilai k = ….
A. 1/3
B. ¼
C. 1/6
D. 1/8
E. 1/12
Pembahasan:
P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) = 1
Jawaban: B
