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) Responses 1 1 0.01 0.01 0.10 0.10 0.20

Answer 1

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

Sum of all probabilities:
0.25 + 0.18 + 0.30 + 0.17 + x = 1

Now, substitute the given values:
0.25 + 0.18 + 0.30 + 0.17 + x = 1
0.90 + x = 1

Subtract 0.90 from both sides:
x = 1 - 0.90
x = 0.10

Therefore, the value of x in this probability model is 0.10.
