dua dadu dilempar secara bersamaan. peluang dadu pertama muncul mata dadu genap dan dadu kedua muncul mata dadu prima adalah? Kasih tau caranya ya

n(s) = 6^2 = 36

n(a) = {(2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6)} = 18

n(p) = {(1,2) (2,2) (3,2) (4,2) (5,2) (6,2) (1,3) (2,3) (3,3) (4,3) (5,3) (6,3) (1,5) (2,5) (3,5) (4,5) (5,5) (5,6)} = 18

P (a ∪ p) =n(a) + n(b) / n(s)
P (a ∪ p) = 18+18/36
P (a ∪ p) = 36/36 = 1
