if its a dice then the odds are 5%2F6=0.8333
explanation:
The are 1,2,3,4,5,6, each one with a probability of 1%2F6.
How many are larger than 1?
Answer is :2,3,4,5, and 6
That means we can add the probability of each one (we do not have to subtract anything since they are independent) so we end up with
1%2F6%2B1%2F6%2B1%2F6%2B1%2F6+%2B1%2F6=5%2F6=+0.8333
