The correct preposition is 'on' when referring to working on a task or project. 'Working on a project' is the standard phrase.
A random variable $Y$ follows a normal distribution with mean $200$ and standard deviation $10$. Compare:
Quantity A: The probability that $Y > 220$
Quantity B: $\dfrac{1}{6}$
The value $220$ is $\dfrac{220 - 200}{10} = 2$ standard deviations above the mean.
For a standard normal distribution, the probability that $Z > 2$ is approximately $0.0228$ (about $2.28\%$).
Quantity B $= \dfrac{1}{6} \approx 0.1667$.
Since $0.0228 < 0.1667$, Quantity A is less than Quantity B.
Therefore Quantity B is greater.
