How do I find the deviation of each x-value from the expected value of 0.97?
The chart looks like this...
x P(x) x-u
0 0.24 ?
1 0.55 ?
2 0.21 ?

You have no measure of variability.
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions/probabilities in terms of Z scores.
Z scores is your score in terms of standard deviations.
Z = (score-mean)/SD
I hope this helps.
