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
0.20
0.01
0.10
Given that probabilities must sum to 1, the value of x can be calculated by subtracting the sum of the other probabilities from 1:
0.25 + 0.18 + 0.30 + 0.17 + x = 1
0.90 + x = 1
x = 0.10
Therefore, the value of x is 0.10.
