Answer 1

1/2

The probailty of an event A is:

● P(A) = ( outcomes that give A) / (total number of possible outcomes)

Let A be the event in wich we get an even number.

● The sample space is {2,4,6}

So there are 3 possible outcomes that give A .

The six-sided dice has 6 outcomes

● { 1,2,3,4,5,6}
