Question

Tolong dong pake caranya

Answer 1

8. Teorema Jabat Tangan
= n x (n-1)/2
= 10 x (10-1)/2
= 5 x 9 = 45 kali

9. Frekuensi harapan
= P(A) x n
= 3/4 x 100
= 75 kali

10. Peluang tidak saling lepas
P(A) = peluang sepakbola
P(B) = peluang bulu tangkis

P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∪B) = 30/48 + 26/48 - 12/48
P(A∪B) = 30 + 26 - 12/48
P(A∪B) = 44/48 = 11/12
