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 0.01 0.01 0.10 0.10 1 1 0.20 0.20
To find the value of x, we need to calculate the sum of the probabilities and set it equal to 1.
0.25 + 0.18 + 0.30 + 0.17 + x = 1
Solving for x:
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.
