Two events are considered *mutually exclusive* if they cannot occur at the same time. For example, consider a single coin flip: the events “tails” and “heads” are mutually exclusive because we cannot get both tails and heads on a single flip.

We can visualize two mutually exclusive events as a pair of non-overlapping circles. They do not overlap because there is no outcome for one event that is also in the sample space for the other:

What about events that are not mutually exclusive? If event *A* is rolling an odd number and event *B* is rolling a number greater than two, these events are not mutually exclusive. They have an intersection of *{3, 5}*. Any events that have a non-empty intersection are not mutually exclusive.

### Instructions

**1.**

In **quiz.py** we have the following variables: `events_1`

, `events_2`

, and `events_3`

. Given the two events outlined in these exercises, fill in the variables as either `"mutually exclusive"`

or `"not mutually exclusive"`

.

We have a bag of five marbles: three are green and two are blue. Suppose that we pick one marble from the bag. Event A is that the marble is green. Event B is that the marble is blue. Are these events mutually exclusive?

Fill your answer in the `events_1`

variable where it says `"insert answer here"`

. After filling out your answer in **quiz.py**, hit run.

**2.**

We roll a die once. Event A is rolling an odd number. Event B is rolling a number greater than four. Are these events mutually exclusive?

Fill your answer in the `events_2`

variable where it says `"insert answer here"`

. After filling out your answer in **quiz.py**, hit run.

**3.**

We roll a die once. Event A is rolling an even number. Event B is rolling a number less than two. Are these events mutually exclusive?

Fill your answer in the `events_3`

variable where it says `"insert answer here"`

. After filling out your answer in **quiz.py**, hit run.
