Frekuensi harapan munculnya mata dadu bilangan prima pada percobaan pelemparan sebuah dadu sebanyak 300 kali adalah...

bilangan prima = 2, 3, 5

P(A)
= n(A) / n(s)
= 3 / 6
= 1/2

Fh
= n . P(A)
= 300 . 1/2
= 150

bilangan prima = 2, 3, 5. = 3 n(a)
n(s) = 6. karena mata dadu ada 6.
P(a) = n(a)/n(s) = 3/6 = 1/2.

Frekuensi = P(a) × banyak percobaan
= 1/2 × 300
= 150
