# die roll quiz answers
Create a die when the BBC micro:bit is shaken
These are the answers to the [die roll quiz](/lessons/die-roll/quiz).
## 1. Create a variable named 'roll' that will be randomly assigned to a number between 0 and 5.
<br/>
```blocks
let roll = Math.random(6)
```
## 2. If the variable "roll" equals 5, write the code that will plot the image below

<br/>
```blocks
let roll = Math.random(6)
if (roll == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .
`)
}
```
## 3. You will use an `else if` condition if "roll" is equal 4. Write the `else if` statement that will display the plot image below

```blocks
let roll = Math.random(6)
if (roll == 5) {
basic.showLeds(`

. # . # .
. . . . .
. # . # .
`)
} else if (roll == 4) {
basic.showLeds(`

. # . # .
. . . . .
`)
}
