Answer:
3x2y−3xy+12x−12

Answer:
1/6
Step-by-step explanation:
Probability is a chance of an event taking place.
Probability = (favorable outcome)/(total outcome)
There are 3 even sides in a dice.
P(even) = 3/6 = 1/2
There are 2 numbers that are greater than 4 in a dice.
P(x>4) = 2/6 = 1/3
P(even and x>4) = 1/2 × 1/3 = 1/6
