Question
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
0.10
0.10

0.01
0.01
0.20
To find the value of x, we need to add up the probabilities of Y, C, A, R, and E and subtract it from 1.
0.25 + 0.18 + 0.30 + 0.17 + x = 1
0.90 + x = 1
x = 1 - 0.90
x = 0.10
Therefore, the value of x is 0.10.
