The probability that her favorite color is not red is equal to 1 minus the probability that her favorite color is red. Therefore, we can find this probability by adding up the percentages of all the other colors and subtracting from 100%.

P(not red)=100% - P(red)=100% - 18% = 82%

So the probability that her favorite color is not red is 0.82.
