Create a dice when the @boardname@ is shaken

These are the answers to the dice roll quiz.

1. Create a variable named 'roll' that will be randomly assigned to a number between 0 and 5.

let roll = Math.random(6)

2. If the variable "roll" equals 5, write the code that will plot the image below

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

let roll = Math.random(6)
if (roll == 5) {
    basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .
`)
} else if (roll == 4) {
    basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .
`)
}

Note: students are only required to write the bottom half of this answer, starting with "else if".

. # . # .
. . . . .
`)
} else if (roll == 3) {

if (roll == 3) {
    basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # . # .
. . . . .
`)
} else if (roll == 2) {

`)
}
