Explanation / Answer

1)

The probability of a certain event is 1.

And the probability that event will never occur (that is an impossible event) is zero.

2)

Every person must die. So the event that you will live forever" is an impossible event. So its probability is zero.

Octopus can't fly so it is also an impossible event. So its probability is zero.

3)

By the complement rule, the probability of obataining a number other than 3 is

1 - 0.167 = 0.833

4)

Event: "Getting a interger between 1 and 6 (inclusive) when we roll a fair six sided die". When we roll a fair six sided die possible outcomes are 1, 2, 3, 4, 5, or 6.

So this event is a certain event. Its probability is 1.
