Frekuensi harapan mata dadu >3​

Jawaban:

*mencari ruang sampel

dadu –> 6 sisi –> 1, 2, 3, 4, 5, 6

n(S) = 6

*misal A = kejadian muncul mata dadu 3

kejadian mata dadu 3 = 3

n(A) = 1

*mencari peluang

P(A) = frac{n(A)}{n(S)} = frac{1}{6}P(A)=

n(S)

n(A)

=

6

1

*mencari frekuensi harapan

Fh(A) = P(A) x n

= frac{1}{6}

6

1

x 150 kali

= 25 kali
