dua buah dadu dilempar bersamaan, peluang muncul mata dadu berjumlah bilangan prima

ne jawabannya dekku...

Mata dadu berjumlah bilangan prima (A)
= {(1,1),(1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(4,1),(4,3),(5,2),(5,6),(6,1),(6,5)}

n(A) = 15
n(S) = 6 × 6 = 36

P(A) = n(A)/n(S)
P(A) = 15/36
P(A) = 5/12
