If the table below represents a probability model based on observed frequencies, what is the value of ?
Y C A R E S
P(Y) 0.25 0.18 0.30 0.17
(1 point)
x
x
0.10
1
0.01
0.20
The sum of all the probabilities in a probability model must equal 1.
0.25 + 0.18 + 0.30 + 0.17 + x = 1
x = 1 - 0.25 - 0.18 - 0.30 - 0.17
x = 0.10
Therefore, the value of x is 0.10.
