## Step 1: Calculate the total number of skittles.### We sum the number of skittles of each color:
.## Step 2: Calculate the probability of getting a blue skittle.### The probability is the number of blue skittles divided by the total number of skittles:
. Converting to percentage, we get
.## Step 3: Calculate the probability of getting a red skittle.### The probability is the number of red skittles divided by the total number of skittles:
. Converting to percentage, we get
.## Step 4: Calculate the probability of getting a green skittle.### The probability is the number of green skittles divided by the total number of skittles:
. Converting to percentage, we get
.## Step 5: Calculate the probability of getting a red OR a green skittle.### The probability is the sum of the probabilities of getting a red skittle and a green skittle:
. Converting to percentage, we get
