Given:
the plant food requires 5 and 1/2 gallons of water
The measuring container has marks for only pints
So, we need to convert from gallon to pints
1 gallon = 8 pints
So, 5 1/2 gallons =

so, She will use 44 pints of water.
What are you supposed to be solving for?
You can tell this is a binomial distribution since there is specific failure or success (getting a defective is success, for example).
X~B(5, 0.01)
P(X≥1)= 1-P(X≤1)
=1-(0.999)
=9.80×10⁴ probability of getting at least one that is defective.
Hope I helped :)
