Answer:
5/9
Step-by-step explanation:
To have an even number (let's call it E) OR a number greater than 9 (let's call it N), you can have EITHER of them.
So, to calculate the probability, you need to find the probability of having E and then the probability of having N... then ADD them together.
To calculate the probability, just look on the image.
Probability of having an even number: 18 (red circles)
Probability of having a number greater than 9 (that is NOT already counted in the even scenario): 2 (within the blue zone, but not red)
We don't count a same possibility (like 6,4) twice, only once.
Total: 18 + 2 = 20
Out of 36 possibilities
So, probability is 20/36, or 10/18 or 5/9.
