If the table below represents a probability model based on observed frequencies, what is the value of ?
Y
C
ARE
S
P(Y) 0.25 0.18 0.30 0.17
(1 point)
0.01
0.10
1
0 20
To find the value of ?, we need to sum up the probabilities of all possible outcomes:
0.25 + 0.18 + 0.30 + 0.17 = ?
This equals 0.9.
Therefore, the value of ? is 0.1.
