Step-by-step explanation:
The probability that the seed will produce a plant is almost certain at 90%

Notice that equality holds when either

or

, so these should be included in the solution set.
Now, since the coefficient of the leading term is positive, we know the parabola opens upward, which means we know that

when

and

, and that

when

.
So the solution set is the interval

.
