Question

What is the probability of rolling a number higher than 3 on a six sided dice?

Answer 1

It's `1/2=50%`

Explanation:

There are possibilities, each with the same probability `1/6`

We are looking for `4,5 or6`

Since this is a OR -situation, you ADD the three probabilities:
`P(>3)=P(4)+P(5)+P(6)=1/6+1/6+1/6=3/6=1/2=50%`
