A rare plant will only produce flowers from 10% of the seeds planted. Kelsey plants two seeds of this plant. What is the probability that neither seed produces a plant with flowers? Express your answer as a percentage rounded to the nearest whole number.
The probability that both seeds do not produce a plant with flowers is (0.9)^2 = 0.81.
Converting this to a percentage and rounding to the nearest whole number, the probability is 81%.
