Answer:
1/2
Explanation:
Probability is essentially (# times a specific event occurs) / (# times the general event occurs).
Here, the specific event is rolling a number that is divisible by 2. The numbers divisible by 2 from 1 to 6 are 2, 4, and 6. Since there are 3 such numbers, the specific event can occur 3 times.
The general event is simply rolling any number. Because there are 6 numbers we can roll, the number of times the general event can occur is 6.
So, the probability is 3/6 = 1/2.
