To find the value of x, we need to use the fact that the sum of all probabilities in a probability model must equal 1.

Adding all the given probabilities:
0.25 + 0.18 + 0.30 + 0.17 + x = 1

Now, plug in the known values and solve for x:
0.90 + x = 1
x = 0.10

Therefore, the value of x in the table is 0.10.
