If the table below represents a probability model based on observed frequencies, what is the value of x ?
Y C A R E S
P(Y) 0.25 0.18 0.30 0.17 x (1 point)

0.10
Since the sum of probabilities should add up to 1, we can calculate the value of x by subtracting the sum of P(Y) for Y, C, A, R, and E from 1:
1 - (0.25 + 0.18 + 0.30 + 0.17) = 1 - 0.90 = 0.10
Therefore, the value of x is 0.10.
