Question

You roll a six-sided number cube find the probability of rolling each the following.P(even or odd)

Answer 1

We are given a six-sided number cube. When rolling this cube the possible outcomes are 1, 2, 3, 4, 5, 6. We are asked to determine the probability that one of the numbers we get is even. From all the possible outcomes 3 of these are even, therefore, the probability of getting an even number is:

`P(\text{even)}=(3)/(6)=0.5`

Therefore, there's a 50% chance the number we get is even.

The probability that one one of the outcomes is odd is given by the fact that from all the possible outcome 3 are odd numbers, therefore, the probability is:

`P(\text{odd)}=(3)/(6)=0.5`

The probability of these outcomes to be even or odd is the sum of both probabilities, that is:

`P(\text{even or odd)=P(even)+P(odd)=0.5+0.5=1}`
